Quantum Experiments and the Foundations of Physics

For a more fundamental look at what I am looking for in guidance, follow this talk by Lubos. I most defintiely could be called a crackpot, but really, my heart and intentions are honourable and I will try to do justice to those things I am learning.

Dirac's Hidden Geometries

When one is doing mathematical work, there are essentially two different ways of thinking about the subject: the algebraic way, and the geometric way. With the algebraic way, one is all the time writing down equations and following rules of deduction, and interpreting these equations to get more equations. With the geometric way, one is thinking in terms of pictures; pictures which one imagines in space in some way, and one just tries to get a feeling for the relationships between the quantities occurring in those pictures. Now, a good mathematician has to be a master of both ways of those ways of thinking, but even so, he will have a preference for one or the other; I don't think he can avoid it. In my own case, my own preference is especially for the geometrical way.

For me the maths are not easy yet following experimental processes help me to direct my thinking. If we enage in philsophical talk then th eessence of this talk had to have a logic basis to it that is currently being expressed as far as I understood it. BUt even this logic take on new methods to expand and make room for the proceses for which we are engaging in talking about.

It is indeed a tuff struggle to remain current in thinking and stil embue our lives with the philosophies we hold in front of us?

The whole point is a comparison was made and reduced to philosophical idealizations, and was diverted from the math? There were consisent methods established that leads us to todays information. Is your philsophy based on what we now know?

Purity of thought around these issues, would have helped me to recognize that reducing these things to "philsophical debate" had to follow experimental processes, and that what I was trying to show, points towards the current work in scattering amplitudes(new models used?) to push perception.

How would our thinking change in how we percieve according to the new models we used for moving perception beyond what it currently houses?



Test of the Quantenteleportation over long distances in the duct system of Vienna Working group Quantity of experiment and the Foundations OF Physics Professor Anton Zeilinger

Quantum physics questions the classical physical conception of the world and also the everyday life understanding, which is based on our experiences, in principle. In addition, the experimental results lead to new future technologies, which a revolutionizing of communication and computer technologies, how we know them, promise.

In order to exhaust this technical innovation potential, the project "Quantenteleportation was brought over long distances" in a co-operation between WKA and the working group by Professor Anton Zeilinger into being. In this experiment photons in the duct system "are teleportiert" of Vienna, i.e. transferred, the characteristics of a photon to another, removed far. First results are to be expected in the late summer 2002.

Further research of Anton Zeilinger:Scientific Publications Prof. Anton Zeilinger

Quantum teleportation, step by step. Although the details of their experiments differ, both the NIST and Innsbruck teams have achieved deterministic teleportation of a quantum state between trapped ions:

First, an entangled state of ions A and B is generated, then the state to be teleported -- a coherent superposition of internal states -- is created in a third ion, P.

The third step is a joint measurement of P and A, with the result sent to the location of ion B, where it is used to transform the state of ion B (step 4).

The state created for P has then been teleported to B

By taking advantage of quantum phenomena such as entanglement, teleportation and superposition, a quantum computer could, in principle, outperform a classical computer in certain computational tasks. Entanglement allows particles to have a much closer relationship than is possible in classical physics. For example, two photons can be entangled such that if one is horizontally polarized, the other is always vertically polarized, and vice versa, no matter how far apart they are. In quantum teleportation, complete information about the quantum state of a particle is instantaneously transferred by the sender, who is usually called Alice, to a receiver called Bob. Quantum superposition, meanwhile, allows a particle to be in two or more quantum states at the same time

The history contained in this post should direct any further perceptions I have, but you know, I still believe we will judge ourselves as to the constitutions with which we had choosen to exemplify in our continuing evolution of soul.

Scattering Amplitudes

So where has "experimentation" taken us to today?

Stanford Encyclopedia of Philosophy
Under the Heading of Bell's Theorem

Zeilinger:

The quantum state is exactly that representation of our knowledge of the complete situation which enables the maximal set of (probabilistic) predictions of any possible future observation. What comes new in quantum mechanics is that, instead of just listing the various experimental possibilities with the individual probabilities, we have to represent our knowledge of the situation by the quantum state using complex amplitudes. If we accept that the quantum state is no more than a representation of the information we have, then the spontaneous change of the state upon observation, the so-called collapse or reduction of the wave packet, is just a very natural consequence of the fact that, upon observation, our information changes and therefore we have to change our representation of the information, that is, the quantum state. (1999, p. S291).

Of course tryng infiltrate this undertanding inthose who have progressed before is the way in which we are lead to other ideas and works in progress.

Lubos Motl:

In the Minkowski space and de Sitter space, we can safely define the energies according to the strategy above, and we may also determine the time evolution, but only from -infinity to +infinity. If these infinities really appear in the far past and the far future, we call the evolution operator "S-matrix". String theory allows us to calculate the S-matrix (another example that we do call an "observable") for all particles in the spectrum which includes the scattering of gravitons. We don't have to insert our knowledge about the problematic "bulk" observables: string theory automatically tells us not only the right answers but also the right questions. "It is the S-matrix you should calculate, silly," she says. It also tells us what are the corresponding evolution observables for anti de Sitter space.

Someone may therefore convince you that the S-matrix is the only meaningful observable that has any physical meaning in a quantum theory of gravity. This sentence is both deep, if an appropriate interpretation is adopted, as well as discouraging.

Plato:

It is indeed a struggle for me to be clear in this regard, but hopefully, recogizing the requirements of the physicist and the theoretician, that such scholar attributes can be waivered for the commoner?

Scattering Amplitudes?

SLAC E158: Measuring the Electron's WEAK Charge

At SLAC and elsewhere in the 1990s, precision measurements probing quantum effects from physics at higher energy scales were very successful. Precision electroweak measurements accurately predicted the mass of the top quark before it was discovered at the Tevatron at Fermilab, and they were cited in the awarding of the 1999 Nobel Prize to Veltmann and t'Hooft, which recognized their work in developing powerful mathematical tools for calculating quantum corrections and demonstrating that the Standard Model was a renormalizable theory. The discovery and mass measurement of the top quark at Fermilab's Tevatron and the precise Z0 boson mass measurement from CERN experiments added to well established values for other Standard Model parameters, to allow predictions for the only Standard Model parameter not yet measured, the Higgs mass.

Symmetry

asymmetric insight by Heather Rock Woods

Marciano agrees that the experiment contributes to the coming frontier-energy physics. "Perhaps just as important as its final result, E158 provides a clear demonstration that this technique can be employed at the proposed ILC by scattering its high-energy polarized electron beam off a fixed target of electrons. With the higher energy and much larger effective luminosity provided by that facility, unprecedented precision studies of polarized electron-electron scattering will be possible. These studies will probe deeply for virtual particles that pop in and out of existence and other signs of new physics."

In revealing the character of the symmetry-defying weak force, E158 has provided tools and exposed dead ends for the coming climb to higher peaks.

Special holonomy manifolds in string theory

So what instigated my topic today and Hypercharge make sits way for me to reconsider, so while doing this the idea of geoemtries and th eway in which we see this uiverse held to the nature of it's origination are moving me to consider how we see in ths geometrical sense.

The resurgence of ideas about the geometries taking place are intriguing models to me of those brought back for viewing in the Sylvester surfaces and B field relations held in context of the models found in the >Wunderkammern.

This paragraph above should orientate perception for us a bit around methods used to see in ways that we had not seen before. This is always very fascinating to me. What you see below for mind bending, helps one to orientate these same views on a surface.



Hw would you translate point on a two dimensional surface to such features on the items of interest on these models proposed?



Part of my efforts at comprehension require imaging that will help push perspective. In this way, better insight to such claims and model methods used, to create insight into how we might see those extra 10 dimensions, fold into the four we know and love.



G -> H -> ... -> SU(3) x SU(2) x U(1) -> SU(3) x U(1).

Here, each arrow represents a symmetry breaking phase transition where matter changes form and the groups - G, H, SU(3), etc. - represent the different types of matter, specifically the symmetries that the matter exhibits and they are associated with the different fundamental forces of nature

If one held such views from the expansitory revelation, that our universe implies at these subtle levels a quantum nature, then how well has our eyes focused not only on the larger issues cosmology plays, but also, on how little things become part and parcel of this wider view? That the quantum natures are very spread, out as ths expansion takes place, they collpase to comsic string models or a sinstantaneous lightning strikes across thei universe from bubbles states that arose from what?

So knowing that such features of "spherical relation" extended beyond the normal coordinates, and seeing this whole issue contained within a larger sphere of influence(our universe), gives meaning to the dynamical nature of what was once of value, as it arose from a supersymmetrical valuation from the origination of this universe? If Any symmetry breaking unfolds, how shall we see in context of spheres and rotations within this larger sphere, when we see how the dynamcial propertties of bubbles become one of the universes as it is today? Genus figures that arise in a geometrodynamcial sense? What are these dynacis within context of the sphere?



So as I demonstrate the ways in which our vision is being prep for thinking, in relation to the models held in contrast to the nature of our universe, how are we seeing, if we are moving them to compact states of existance, all the while we are speaking to the very valuation of the origination of this same universe?



Holonomy (30 Dec 2005 Wiki)

Riemannian manifolds with special holonomy play an important role in string theory compactifications. This is because special holonomy manifolds admit covariantly constant (parallel) spinors and thus preserve some fraction of the original supersymmetry. Most important are compactifications on Calabi-Yau manifolds with SU(2) or SU(3) holonomy. Also important are compactifications on G2 manifolds.

Wave Function and Summing over Histories

Dealing with a 5D World

A black hole is an object so massive that even light cannot escape from it. This requires the idea of a gravitational mass for a photon, which then allows the calculation of an escape energy for an object of that mass. When the escape energy is equal to the photon energy, the implication is that the object is a "black hole".

Paul Valletta:

Being that photons are the energy needed for observation by ‘observers’, what happens to a system when the limit of observation is at a minimum ie single photons?

Of course, I could be wrong?:)

"Which Way"? :)

Bohr's principle of complementarity predicts that in a welcher weg ("which-way") experiment, obtaining fully visible interference pattern should lead to the destruction of the path knowledge. Here I report a failure for this prediction in an optical interferometry experiment. Coherent laser light is passed through a dual pinhole and allowed to go through a converging lens, which forms well-resolved images of the respective pinholes, providing complete path knowledge.

Maybe comparative views can be held in context of the graviton as a force carrier as well, when thinking about your question above? There is a "certain influence" over top of your question?

Will this help us to move beyond the standard model?

Sometimes such a change in perception is necessary, to look to what is "contained" in the "wave function," yet there is something left over, that we had not analyzed yet?

How shall we describe this in context of the fifth force? Such a solution recognizes the advances made in GR with the encapsulation of Maxwell's equations and as well the leading indicators to such geometries, that we had witness in working to the Riemann sphere. BUt beyond this in compactive states of existance(quantum mechanics), how shall such views be encapsulated?

An Introduction to String Theory A Talk by Steuard Jensen, 11 Feb 2004

So how does all this come together into a physical theory? It turns out that the proper procedure is to construct every possible diagram allowed by the theory (for a given state of input and output particles and how they're moving) and add up the corresponding complex numbers. The result is essentially the "wave function" for that specific input-output state combination, and by squaring that number you can determine the probability that the given input will result in the given output. Doing that is how theorists at particle accelerators earn their keep.

Under these principals how shall a photon react to the enviroment in which it is moving? Moving, to encapsulate such views by moving to a fifth force is necessary.



While it is not always easy to see what is taking place, by perserverance I hope to one day understand the fullscope :)


Oskar Klein Collegiate Professorship Inaugural Lecture: "The World in Eleven Dimensions"by Michael Duff




Why?

Such a view of the photon held in context of the fifth force is the joining of gravity and light?

The least-action principle is an assertion about the nature of motion that provides an alternative approach to mechanics completely independent of Newton's laws. Not only does the least-action principle offer a means of formulating classical mechanics that is more flexible and powerful than Newtonian mechanics, [but also] variations on the least-action principle have proved useful in general relativity theory, quantum field theory, and particle physics. As a result, this principle lies at the core of much of contemporary theoretical physics.

Thomas A. Moore "Least-Action Principle" in Macmillan Encyclopedia of Physics, John Rigden, editor, Simon & Schuster Macmillan, 1996, Volume 2, page 840.

It is far better to understand the workings then just have wave a hand at it and said what a "crock of this or that"? What is worth while, that has been put into thinking here?

You just can't sweep it under the rug, and all is fine. Models, help in this regard, and if your comments were deleted becuase you didn't tow the party line, then should you have followed such orders and dismiss this model(your model?) which motivates to comprehension?

Some seem to think so, while they are held in the "same regardas arvix?" to which they themselves have handed out their criticisms and deletions. People who understand this statement, will know exactly what I mean. Those that don't. It wasn't meant for you :)

Laval Nozzle and the Blackhole

Often times model changes help perspective, where previously idealization will be contained. Moving beyond the experimental grasp for new ways in which to interpret, require a mode and offensive into producing new variations of ole thngs held in context? Ths is why such models like string that began in one mode in terms of quark confinement have now bloossomed into modes cocnerned with quantum gravity.



Discovering new dimensions at LHC

More dramatically still, the LHC could produce fundamental string relations of our familiar particles, such as higher-spin relatives of electrons or photons. There is also a possibility that, owing to the now much stronger gravitational interactions, microscopically tiny black holes could be produced with striking signals.

Once idealization and understanding developed in quark Confinement, it is understood the shift to the metric and the idealization of that measure became a property I found in the way we now deal with the perceptions containing dimensional significance? Strng Theory, that had graduade from the model apprehensions early on, here to a more fundamental pursuate of how we see in those extra dimensions, compact as they may be?

Acoustic Metric (29 Dec 2005 Wiki)

In mathematical physics, a metric (mathematics) describes the arrangement of relative distances within a surface or volume, usually measured by signals passing through the region – essentially describing the intrinsic geometry of the region. An acoustic metric will describe the signal-carrying properties characteristic of a given particulate medium in acoustics, or in fluid dynamics. Other descriptive names such as sonic metric are also sometimes used, interchangeably.

Since "acoustic" behaviour is intuitively familiar from everyday experience, many complex "acoustic" effects can be confidently described without recourse to advanced mathematics. The rest of this article contrasts the "everyday" properties of an acoustic metric with the more intensely studied and better-documented "gravitational" behaviour of general relativity

On the Universality of the Hawking Effectby William G. Unruh and Ralf Schutzhold

Addressing the question of whether the Hawking effect depends on degrees of freedom at ultra-high (e.g., Planckian) energies/momenta, we propose three rather general conditions on these degrees of freedom under which the Hawking effect is reproduced to lowest order. As a generalization of Corley’s results, we present a rather general model based on non-linear dispersion relations satisfying these conditions together with a derivation of the Hawking effect for that model. However, we also demonstrate counter-examples, which do not appear to be unphysical or artificial, displaying strong deviations from Hawking’s result. Therefore, whether real black holes emit Hawking radiation remains an open question and could give non-trivial information about Planckian physics.

It is important that when thinking about this universality that the derivations of such thinking is understood by me so I ahve to lay it out in a sequence that suports the end part of this post so that it is brought togher in a nice way. I bold mark thos epoints that help greatly in my understanding.

Acoustic_theory(28 Dec 2005 Wiki)

Acoustic theory is the field relating to mathematical description of sound waves. It is derived from fluid dynamics. See acoustics for the engineering approach.

The propagation of sound waves in air can be modeled by an equation of motion (conservation of momentum) and an equation of continuity (conservation of mass). With some simplifications, in particular constant density, they can be given as follows:


where is the acoustic pressure and is the acoustic fluid velocity vector, is the vector of spatial coordinates x,y,z, t is the time, ρ0 is the static density of air and c is the speed of sound in air.

Fluid Dynamics (28 Dec 2005 Wiki)

Fluid dynamics offers a mathematical structure, which underlies these practical discipines, that embraces empirical and semi-empirical laws, derived from flow measurement, used to solve practical problems. The solution of a fluid dynamics problem typically involves calculating for various properties of the fluid, such as velocity, pressure, density, and temperature, as functions of space and time

So these ideas in terms of analogies help to push forarwd understanding where we might have been limited in our views before. I know, they certainly help me.

"Analogue Gravity"
by Carlos Barceló and Stefano Liberati and Matt Visser

Abstract

Analogue models of (and for) gravity have a long and distinguished history dating back to the earliest years of general relativity. In this review article we will discuss the history, aims, results, and future prospects for the various analogue models. We start the discussion by presenting a particularly simple example of an analogue model, before exploring the rich history and complex tapestry of models discussed in the literature. The last decade in particular has seen a remarkable and sustained development of analogue gravity ideas, leading to some hundreds of published articles, a workshop, two books, and this review article. Future prospects for the analogue gravity programme also look promising, both on the experimental front (where technology is rapidly advancing) and on the theoretical front (where variants of analogue models can be used as a springboard for radical attacks on the problem of quantum gravity).

and here......

Parentani showed that the effects of the fluctuations of the metric (due to the in-going flux of energy at the horizon) on the out-going radiation led to a description of Hawking radiation similar to that obtained with analogue models. It would be interesting to develop the equivalent formalism for quantum analogue models and to investigate the different emerging approximate regimes.

I am always interested in how science might take these analogies in concert with how we understand blackhole horizon abilites. To exemplify the understanding of where "this place of virtual reality might issue from such a ground state" might be, in terms of what might flow one way, and what will flow in another, as photon pairs do from around the blackhole.

How far can this be taken as we look to understand Hawking radiation? How would such constrictions pave the way for sound emitted and held in context of Hawking Radiation, flowing through a pipe? We've had our lessons from Cosmic Variance on this, but would it have ever been taken this far?

Well, I still like to think about the gravitational comparisons here, so I would be very happy to have found some geometrical propensities towards how the horizon would have given us a good picture of what "first principle" might be as we look at the nature of hawking radiation, and how the standard model is featured from that horizon. So of course I am thinking deeply about all the things I have been learning.

I hope one day a comprehensive picture forms so that I can finally understand what is going on?

Further "Analogy" sought by me to help my perspective.

Bubble World and Geometrodynamics

Tiny Bubbles

Making Sense of the Nonsensical

From this experiment it is apparent that interference is destroyed by a "which-way" marker and that it can be restored through erasure of the marker, accomplished by making the appropriate measurement on the entangled partner photon p.

In this set up, the "which-way" measurement does not alter the momentum or position of the photons to cause destruction of the interference pattern. We can think of the loss of interference as being due only to the fact that the photons are entangled and that the presence of the quarter wave plates changes this entanglement. The interference pattern can be brought back through the erasure measurement because of the entanglement of the photons, and the way that the presence of the quarter wave plates and polarizer changes the entanglement.

It is very obvious I need some time to digest and listen carefully here. Of course I draw from Wiki quite regularly and I hate to think such efforts to destroy a concerted effort by those whose hearts are pure, for leading others into the correct methods, would not resort ot the efforts and likes of those Lubos has brought to our attention.

ON the note below taken from Lubos update, it is without thinking that I might have lured others into the state of complacency without fully understanding, and hence my part in this effort less than kind? So I'll draw back for a bit here and try and digest what I learnt and see if I can get it together.

Lubos Motl:

Note added later: let me mention that Kastner has submitted another paper criticizing Afshar's conclusions. In my opinion both Unruh as well as Kastner replace Afshar's experiment by a completely different experiment that does not capture the main flaw of Afshar's reasoning. The main flaw is that Afshar does not realize that for a tiny grid, only a very tiny percentage of photons is used to observe the wave-like properties of light; these are essentially the photons for which the which-way information is completely lost. Because most photons go through the lens without any interactions and interference, Afshar is not allowed to say that he observes the wave-like phenomena with visibility close to one. In fact, it is close to zero if a consistent set of photons is used to define both V and K.

Here is the paper >Kastner talks too in regards to the content of Afshar experiment.

Why the Afshar Experiment Does Not Refute ComplementarityR. E. Kastner

ABSTRACT. A modified version of Young’s experiment by Shahriar Afshar demonstrates that, prior to what appears to be a “which-way” measurement, an interference pattern exists. Afshar has claimed that this result constitutes a violation of the Principle of Complementarity. This paper discusses the implications of this experiment and considers how Cramer’s Transactional Interpretation easily accomodates the result. It is also shown that the Afshar experiment is analogous in key respects to a spin one-half particle prepared as “spin up along x”, subjected to a nondestructive confirmation of that preparation, and post-selected in a specific state of spin along z. The terminology “which-way” or “which-slit” is critiqued; it is argued that this usage by both Afshar and his critics is misleading and has contributed to confusion surrounding the interpretation of the experiment. Nevertheless, it is concluded that Bohr would have had no more problem accounting for the Afshar result than he would in accounting for the aforementioned pre- and
post-selection spin experiment, in which the particle’s preparation state is
confirmed by a nondestructive measurement prior to post-selection. In addition,
some new inferences about the interpretation of delayed choice experiments are
drawn from the analysis.

1. Introduction.The Young two-slit experiment is a famous illustration of wave-particle duality: a quantum particle emitted toward a screen with two small slits will produce an interference pattern on a detecting screen downstream from the slits. On the other hand, as has been repeatedly demonstrated, if one tries to obtain “which-way” or “which slit” information, the downstream interference

Presence and Entanglement

The equivalence principle(29 DEcember 2005 Wiki)

The accuracy of the gamma-ray measurements was typically 1%. The blueshift of a falling photon can be found by assuming it has an equivalent mass based on its frequency E = hf (where h is Planck's constant) along with E = mc2, a result of special relativity. Such simple derivations ignore the fact that in general relativity the experiment compares clock rates, rather than than energies. In other words, the "higher energy" of the photon after it falls can be equivalently ascribed to the slower running of clocks deeper in the gravitational potential well. To fully validate general relativity, it is important to also show that the rate of arrival of the photons is greater than the rate at which they are emitted

From a layman perspective, I am seeing that the nature of the gravitational field in a circumstance where such "strengths and weaknesses" would have been viable property to our way of seeing?

Lensing by showing us, that such avenues would have found the valution of the photon travelling the quickest route?

So, by changing the face of what we had always agreed upon( encapsulating Gr perspective bulit upon Maxwells creations and the geometries), as the way of energy and matter relation, such presence, would have then said, as a force carrier, that in these two cases, I will always be the way you would interpret my being in gravitational context?? You assume the model

So "always" in the "presence" of a gravitational field?

Fifth force(29 Dec 2005 Wiki)

A few physicists think that Einstein's theory of gravity will have to be modified, not at small scales, but at large distances, or, equivalently, small accelerations. They point out that dark matter, dark energy and even the Pioneer anomaly are unexplained by the Standard Model of particle physics and suggest that some modification of gravity, possibly arising from Modified Newtonian Dynamics or the holographic principle. This is fundamentally different from conventional ideas of a fifth force, as it grows stronger relative to gravity at longer distances. Most physicists, however, think that dark matter and dark energy are not ad hoc, but are supported by a large number of complementary observations and described by a very simple model.

Now, I am having a bit of a problem with the idea of "high energy" being "redshifted" because of the nature of the blackholes gravitational force? IN this case such a presence wouldhave by nature and strength of curvatures would have forced high enegy states to immediately curve backwards. If such blueshigfting is free to penetrate the fastest routes then such signs woudl have gave indication, yet the immediate horizon vicinity, plays havoc on these ideas?

The only way one could ascertain such a state of redshifting, is if "high energy" was evident in proximaty of the blackhole?

Would this be true or false?

Entanglement

Hypercharge (29 Dec 2005 Wiki)

In particle physics, the hypercharge (represented by Y) is the sum of the baryon number B and the flavor charges: strangeness S, charm C, bottomness and topness T, although the last one can be omitted given the extremely short life of the top quark (it decays to other quarks before strong-interacting with other quarks).

Plectics, by Murray Gellman

It is appropriate that plectics refers to entanglement or the lack thereof, since entanglement is a key feature of the way complexity arises out of simplicity, making our subject worth studying.

So by simlifying these ideas of entanglement, we find a model building from the orientation supplied by Murray Gellman, where expeirmentatin and hisortical pursuate have created a legitamate question about what Penrose might ask of a New quantum world view?




Secondly, entanglement issues were progressive, and historically this helps clear up the issues of spooky?


While dissident took us fastidiously to Hooft, I could also interject with Penrose?

But in doing so, such progressions from "simplifed states of plectics" would have taken us through a whole host of idealization in terms's of "dimensional significance," had we adopted Hooft's holographical vision?

If by Hooft's very beginnings, we had thought deeply about the progresions he had taken us too, then how would such developements have looked, if we were the prisoners, and the light behind us, pointed to the shadows on thew wall?

Acoustic Hawking Radiation

What did we learn from studying acoustic black holes? by Renaud Parentani

The study of acoustic black holes has been undertaken to provide new insights about the role of high frequencies in black hole evaporation. Because of the infinite gravitational redshift from the event horizon, Hawking quanta emerge from configurations which possessed ultra high (trans-Planckian) frequencies. Therefore Hawking radiation cannot be derived within the framework of a low energy effective theory; and in all derivations there are some assumptions concerning Planck scale physics. The analogy with condensed matter physics was thus introduced to see if the asymptotic properties of the Hawking phonons emitted by an acoustic black hole, namely stationarity and thermality, are sensitive to the high frequency physics which stems from the granular character of matter and which is governed by a non-linear dispersion relation. In 1995 Unruh showed that they are not sensitive in this respect, in spite of the fact that phonon propagation near the (acoustic) horizon drastically differs from that of photons. In 2000 the same analogy was used to establish the robustness of the spectrum of primordial density fluctuations in inflationary models. This analogy is currently stimulating research for experimenting Hawking radiation. Finally it could also be a useful guide for going beyond the semi-classical description of black hole evaporation.

I am held to a state of profound thinking when I thnk about Einstein in a dream I had. Where his satisfaction was raised, as a surpize, as I listen to the very sound of ice in a glass jug as I slowly turned it? From it, a certain recognition by Einstein held him in amazement as this sound seem to satisfy what he was so long search for in his answers. Yes it is a dream, but this set the stage from what I had been doing previous as I was thinking about the Webber bars and the way research was moving along this avenue to detect grvaiational waves. Movements to the giant Ligo inteferometers, to help us in our pursuate.

I know it is not always easy to understand the thinking here as it is piecemealed, while my minds works to weave a cohesive picture here. So, my apologies.

There is a special class of fluids that are called superfluids. Superfluids have the property that they can flow through narrow channels without viscosity. However, more fundamental than the absence of dissipation is the behavior of superfluids under rotation. In contrast to the example of a glass of water above, the rotation in superfluids is always inhomogeneous (figure). The fluid circulates around quantized vortex lines. The vortex lines are shown as yellow in the figure, and the circulating flow around them is indicated by arrows. There is no vorticity outside of the lines because the velocity near each line is larger than further away. (In mathematical terms curl v = 0, where v(r) is the velocity field.)

Early on the very idea of measuring discrete functions in relation to how we might percieve quark and gluonic natures which arose from the gold ion collisions, raises the very idea of how we may look at the analogies sought to help shape perspective from the horizon, to what is emitted? A Virtual Photon released in pair production at the horizon can become?

While I had come to recognize the differences in thermodynamic principals held in context of the blackhole, the very idea of He⁴raises some interesting scenario's in relation to sound values, while "extreme curvature" had been lead too as a singularity in the blackhole?? This singuarity thought to besimlar to the hawking no bondary proposal would not sit well with how the very nature of the blackhole actually becomes the superfluid that we hav come to recognize in the collider perspectives. This changes things somewhat. How fortunate is it in relation to how we see the supersymmetry that coudl arise inthe action fo symmetry break that signs could be lea dto the nature of the phton release and stretched under the aupsice of theis grvaiutional field?

Overlap of "quantum" and "classical" behaviour

Explanations of Hawking radiation around a black hole often use a description of quantum-mechanical pair production effects occurring on a curved spacetime background. Although this paradigm does not obviously lend itself to a "classical" reinterpretation, research on the black hole membrane paradigm has revealed some overlap between "classical" and "quantum" descriptions.

Plato:

What conditions would have allowed such a scene to be developed in supersymmetrical view, that I had wondered, could such a perfect fluid be the example needed? What blackholes hole would allow such a view to be carried down to this level in gold ion collisions, that we might see the results of string theory, as a useful analogy in the discernation of what can now be brought forward for inspection.

So having recognized the two phases of superfluids that ha dbeen created how woud such analogies move th emind to coisder this other nature of of a helium whose viscosity woud have allowed the sound to travel under the same aupsice held in context of the photon whose naure would havebeen rvealled in redshifting? Would suchj a thing held in context of blue shifting be cancelled out in quark/gluonic phases. that the analogy no longer suits our purpose? While sound i analogy in helium may have revealled the very nature of the superfluid designs we woudl like to see in comparsion to how thephotons are looked at with such short distances?

The laws of black-hole physics, written in this membrane paradigm, are completely equivalent to the corresponding laws of the curved-spacetime paradigm – as long as one restricts attention to the hole's exterior. Consequently, the two paradigms give precisely the same predictions for the outcomes of all experiments or observations that anyone might make outside a black hole …"

What is a Phonon/Photon?

Phonon:

A particle of sound. The energy E of a phonon is given by the Einstein relation, E = hf. Here f is the frequency of the sound and h is Planck's constant. The momentum p of a photon is given by the de Broglie relation, p = h/λ. Here λ is the wavelength of the sound

Photon:

A particle of light. The energy E of a photon is given by the Einstein relation, E = hf. Here f is the frequency of the light and h is Planck's constant. The momentum p of a photon is given by the de Broglie relation, p = h/λ. Here λ is the wavelength of the light.

As you look at the picture above, the very depths to which vision might have been imparted in recognition of this supefluid, what value would be assign something held in the context of the wave nature to have seen it described as a granulization and then thought of in terms of the langangrian perspective as cosmic strings which cross this universe? Make sure you click on the picutre.

Granularity of the Fluid?

Taken from the horizon, how would this fluid look if held in context of William Unruh's previously thought "continous nature" or as a discretium release of Hawking like phonons? It may be "by analogy" help physicists with respect to the nature of gravitational blackholes?

The Single Photon Experiment at Rowan University is a Success!

Einstein/Bohr Debate

"Not often in life has a man given me so much happiness by his mere presence as you have done," Einstein wrote to Bohr. "I have learned much from you, mainly from your sensitive approach to scientific problems."

John G. Cramer

This column is about experimental tests of the various interpretations of quantum mechanics. The question at issue is whether we can perform experiments that can show whether there is an "observer-created reality" as suggested by the Copenhagen Interpretation, or a peacock’s tail of rapidly branching alternate universes, as suggested by the Many-Worlds Interpretation, or forward-backward in time handshakes, as suggested by the Transactional Interpretation? Until recently, I would have said that this was an impossible task, but a new experiment has changed my view, and I now believe that the Copenhagen and Many-Worlds Interpretations (at least as they are usually presented) have been falsified by experiment.

The Single Photon Experiment at Rowan University is a Success!

Entanglement applies to two or more particles even if one of them is used as input to the two slit experiment, it is not applicable to single particle experiments.

Afshars experiment is conducted in such a manner that it is the setup of the experiment coupled with the conservation of momentum that allows us to know exactly which slit the photon has gone through.

Whilst knowing which way the photon has gone we also manage to show the absense of interference with both slits open via intererence minima.

Measurement without “measurement”: Experimental violation of Complementarity and its aftermath

Bohr’s Principle of Complementarity of wave and particle aspects of quantum systems has been a cornerstone of quantum mechanics since its inception. Einstein, Schrödinger and deBroglie vehemently disagreed with Bohr for decades, but were unable to point out the error in Bohr’s arguments. I will report three recent experiments in which Complementarity fails, and argue that the results call for an upgrade of the Quantum Measurement theory. Finally, I will introduce the novel concept of Contextual Null Measurement (CNM) and discuss some of its surprising applications. Web-page: users.rowan.edu/~afshar/ Preprint (published in Proc. SPIE 5866, 229-244, 2005): http://www.irims.org/quant-ph/030503/

Violation of the principle of complementarity, and its implications
Shahriar S. Afshar

Bohr's principle of complementarity predicts that in a welcher weg ("which-way") experiment, obtaining fully visible interference pattern should lead to the destruction of the path knowledge. Here I report a failure for this prediction in an optical interferometry experiment. Coherent laser light is passed through a dual pinhole and allowed to go through a converging lens, which forms well-resolved images of the respective pinholes, providing complete path knowledge. A series of thin wires are then placed at previously measured positions corresponding to the dark fringes of the interference pattern upstream of the lens. No reduction in the resolution and total radiant flux of either image is found in direct disagreement with the predictions of the principle of complementarity. In this paper, a critique of the current measurement theory is offered, and a novel nonperturbative technique for ensemble properties is introduced. Also, another version of this experiment without an imaging lens is suggested, and some of the implications of the violation of complementarity for another suggested experiment to investigate the nature of the photon and its "empty wave" is briefly discussed.

Tiny Bubbles

AS a child, Einsten when given the gift of the compass, immediately reocgnized the mystery in nature? If such a impression could have instigated the work that had unfolded over timein regards to Relativity, then what work could have ever instigated the understanding of the Pea as a constant reminder of what the universe became in the mind of a child, as we sleep on it?

Hills and Valley held in context of Wayne Hu's explanations was a feasible product of the landscape to work with?

'The Princess & The Pea' from 'The Washerwoman's Child'

If Strings abhors infinities, then the "Princess's Pea" was really a creation of "three spheres" emmanating from the "fabric of spacetime?" It had to be reduced from spacetime to a three dimensional frame work?

Spheres can be generalized to higher dimensions. For any natural number n, an n-sphere is the set of points in (n+1)-dimensional Euclidean space which are at distance r from a fixed point of that space, where r is, as before, a positive real number. Here, the choice of number reflects the dimension of the sphere as a manifold.

a 0-sphere is a pair of points
a 1-sphere is a circle
a 2-sphere is an ordinary sphere
a 3-sphere is a sphere in 4-dimensional Euclidean space

Spheres for n ¡Ý 3 are sometimes called hyperspheres. The n-sphere of unit radius centred at the origin is denoted Sn and is often referred to as "the" n-sphere. The notation Sn is also often used to denote any set with a given structure (topological space, topological manifold, smooth manifold, etc.) identical (homeomorphic, diffeomorphic, etc.) to the structure of Sn above.

An n-sphere is an example of a compact n-manifold.

Was it really fantasy that Susskind was involved in, or was there some motivated ideas held in mathematical structure? People like to talk about him without really understandng how such geometrical propensities might have motivated his mind to consider conjectures within the physics of our world?

Bernhard Riemann once claimed: "The value of non-Euclidean geometry lies in its ability to liberate us from preconceived ideas in preparation for the time when exploration of physical laws might demand some geometry other than the Euclidean." His prophesy was realized later with Einstein's general theory of relativity. It is futile to expect one "correct geometry" as is evident in the dispute as to whether elliptical, Euclidean or hyperbolic geometry is the "best" model for our universe. Henri Poincaré, in Science and Hypothesis (New York: Dover, 1952, pp. 49-50) expressed it this way.

You had to realize that working in these abstractions, such work was not to be abandon because we might have thought such abstraction to far from the tangible thinking that topologies might see of itself?


Poincaré Conjecture Proved--This Time for Real
By Eric W. Weisstein

In the form originally proposed by Henri Poincaré in 1904 (Poincaré 1953, pp. 486 and 498), Poincaré's conjecture stated that every closed simply connected three-manifold is homeomorphic to the three-sphere. Here, the three-sphere (in a topologist's sense) is simply a generalization of the familiar two-dimensional sphere (i.e., the sphere embedded in usual three-dimensional space and having a two-dimensional surface) to one dimension higher. More colloquially, Poincaré conjectured that the three-sphere is the only possible type of bounded three-dimensional space that contains no holes. This conjecture was subsequently generalized to the conjecture that every compact n-manifold is homotopy-equivalent to the n-sphere if and only if it is homeomorphic to the n-sphere. The generalized statement is now known as the Poincaré conjecture, and it reduces to the original conjecture for n = 3.

While it is very dificult for me "to see" how such movements are characterized in those higher spaces, it is not without some understanding that such topologies and genus figures would point to the continuity of expression, as "energy and matter" related in a most curious way? Let's consider the non-discretium way in which such continuites work, shall we?

From one perspective this circle woud have some valuation to the makings of the universe in expression, would identify itself where such potenials are raised from the singular function of the circular colliders. Those extra dimensions had to have some basis to evolve too in those higher spaces for such thinking to have excelled to more then mathematical conjectures?

We can also consider donuts with more handles attached. The number of handles in a donut is its most important topological information. It is called the genus.

It might be expressed in the tubes of KK tower modes of measure? That such "differences of energies" might have held the thinking to the brane world, yet revealled a three dimensional perspective in the higher diemnsional world of bulk. These had to depart from the physics, and held in context?



Clay Institute

If we stretch a rubber band around the surface of an apple, then we can shrink it down to a point by moving it slowly, without tearing it and without allowing it to leave the surface. On the other hand, if we imagine that the same rubber band has somehow been stretched in the appropriate direction around a doughnut, then there is no way of shrinking it to a point without breaking either the rubber band or the doughnut. We say the surface of the apple is "simply connected," but that the surface of the doughnut is not. Poincaré, almost a hundred years ago, knew that a two dimensional sphere is essentially characterized by this property of simple connectivity, and asked the corresponding question for the three dimensional sphere (the set of points in four dimensional space at unit distance from the origin). This question turned out to be extraordinarily difficult, and mathematicians have been struggling with it ever since.

While three spheres has been generalized in my point of view, I am somewhat perplexed by sklar potential when thinking about torus's and a hole with using a rubber band. If the formalization of Greene's statement so far were valid then such a case of the universe emblazoning itself within some structure mathematically inclined, what would have raised all these other thoughts towards quantum geometry?

In fact, in the reciprocal language, these tiny circles are getting ever smaller as time goes by, since as R grows, 1/R shrinks. Now we seem to have really gone off the deep end. How can this possibly be true? How can a six-foot tall human being 'fit' inside such an unbelievably microscopic universe? How can a speck of a universe be physically identical to the great expanse we view in the heavens above?

(Greene, The Elegant Universe, pages 248-249)


Was our thoughts based in a wonderful world, where such purity of math structure became the basis of our expressions while speaking to the nature of the reality of our world?


Bubble Nucleation

Some people do not like to consider the context of universe and the suppositions that arose from insight drawn, and held to possibile scenario's. I like to consider these things because I am interested in how a geometical cosistancy might be born into the cyclical nature. Where such expression might hold our thinking minds.


Science and it's Geometries?


Have these already been dimissed by the physics assigned, that we now say that this scenario is not so likely? Yet we are held by the awe and spector of superfluids, whose origination might have been signalled by the gravitational collapse?

Would we be so less inclined not to think about Dirac's Sea of virtual particles to think the origination might have issued from the very warms water of mother's creative womb, nestled.

Spheres that rise from the deep waters of our thinking, to have seen the basis of all maths and geometries from the heart designed. Subjective yet in the realization of the philosophy embued, the very voice speaks only from a pure mathematical realm, and is covered by the very cloaks of one's reason?

After doing so, they realized that all inflationary theories produced open universes in the manner Turok described above(below here). In the end, they created the Hawking-Turok Instanton theory.

The process is a bit like the formation of a bubble
in a boiling pan of water...the interior of this tiny
bubble manages to turn itself into an infinite open
universe. Imagine a bubble forming and expanding at the
speed of light, so that it becomes very big, very quickly.
Now look inside the bubble.

The peculiar thing is that in such a bubble, space and time
get tangled in such a way that what we would call today's
universe would actually include the entire future of the
bubble. But because the bubble gets infinitely large in
the future, the size of 'today's universe' is actually infinite.
So an infinite,open universe is formed inside a tiny, initially
microscopic bubble.
