Superfluidity and the Roton

University of Chicago scientists can create an exotic, particle-like excitation called a roton in superfluids with the tabletop apparatus pictured here. Posing left to right are graduate students Li-Chung Ha and Logan Clark, and Prof. Cheng Chin.

See: Cesium atoms shaken, not stirred, to create elusive excitation in superfluid 


We present experimental evidence showing that an interacting Bose condensate in a shaken optical lattice develops a roton-maxon excitation spectrum, a feature normally associated with superfluid helium. The roton-maxon feature originates from the double-well dispersion in the shaken lattice, and can be controlled by both the atomic interaction and the lattice modulation amplitude. We determine the excitation spectrum using Bragg spectroscopy and measure the critical velocity by dragging a weak speckle potential through the condensate—both techniques are based on a digital micromirror device. Our dispersion measurements are in good agreement with a modified Bogoliubov model. DOI: http://dx.doi.org/10.1103/PhysRevLett.114.055301

The Dark Matter Hunt

Dark matter, the substance making up 85 percent of all the mass in the universe, is invisible. The goal of ADMX is to detect it by turning it into photons, particles of light. Dark matter was forged in the early universe, under conditions of extreme heat. ADMX, on the other hand, operates in extreme cold. Dark matter comprises most of the mass of a galaxy. To find it, ADMX will use sophisticated devices microscopic in size. 
Scientists on ADMX—short for the Axion Dark Matter eXperiment—are searching for hypothetical particles called axions. The axion is a dark matter candidate that is also a bit of a dark horse, even as this esoteric branch of physics goes. See:  Dark horse of the dark matter hunt

Creation of Matter?

"When the photon exits the medium, its identity is preserved," Lukin said. "It's the same effect we see with refraction of light in a water glass. The light enters the water, it hands off part of its energy to the medium, and inside it exists as light and matter coupled together, but when it exits, it's still light. The process that takes place is the same it's just a bit more extreme -- the light is slowed considerably, and a lot more energy is given away than during refraction."

The Axion of the Quark Gluon Pasma?


In physics, an anomalon is a hypothetical type of nuclear matter that shows an anomalously large reactive cross section. They were first noticed in experimental runs in the early 1980s as short tracks in film emulsions or plastic leaf detectors connected to medium-energy particle accelerators. The direction of the tracks demonstrated that they were the results of reactions taking place within the accelerator targets, but they stopped so quickly in the detectors that no obvious explanation for their behavior could be offered. A flurry of theoretical explanations followed, but over time a series of follow-up experiments failed to find strong evidence for the anomalons, and active study of the topic largely ended by the late 1980s.

Professor Emeritus Piyare L. Jain is a particle physicist at University at Buffalo. On December 6, 2006, he claimed discovery of the long-sought axion subatomic particle. [1]
The discovery involved Jain's use of 3-dimensional photographic medium targets in heavy-ion particle accelerators; modern detectors using electronic sensors were unable to detect the axion due to the very short distances and times involved, but the physical medium was able to identify about 1,200 Axion traces over years of experiment. Jain is one of the few currently working physicists with experience with that type of detector, which had been largely abandoned in favor of the modern electronic detectors.

Axions, would also have stopped interaction with normal matter at a different moment than other more massive dark particles. The lingering effects of this difference could perhaps be calculated and observed astronomically. Axions may hold the key to the Solar Corona heating problem.[40] See: Axion

The Sun's outer atmosphere or corona is heated to millions of degrees, considerably hotter than its cool surface or photosphere. Explanations for this long-standing enigma typically invoke the deposition in the corona of non-thermal energy generated by the interplay of convection and magnetic fields. However, the exact physical mechanism driving coronal heating remains unknown. During the past few years, recently built instruments like the Japanese Hinode satellite, the Swedish Solar Telescope in Spain and NASA's Solar Dynamics Observatory (SDO) combined with advanced numerical simulations have revealed a new window into how the Sun's atmosphere is energized. These results directly challenge current theories and highlight the importance of the interface region between the photosphere and corona for understanding how the solar atmosphere is heated. Dr. De Pontieu will present some of these results and describe how NASA's recently selected Interface Region Imaging Spectrograph, which is being built by Lockheed Martin's Solar and Astrophysics Laboratory in Palo Alto, in collaboration with NASA Ames, Smithsonian Astrophysical Observatory (SAO), Montana State University, Stanford University and the University of Oslo, will be able to address many of the outstanding issues and problems.

 An article on IAXO has been published in the September 2014 issue of the CERN Courier. You can see the online version of the article here (link is external), or dowload the full CERN Courier issue here (link is external).

The central component of iAXo is a superconducting toroid magnet. The detector relies on a high magnetic field distributed across a large volume to convert solar axions to detectable X-ray photons. The magnet’s figure of merit is proportional to the square of the product of magnetic field and length, multiplied by the cross-sectional area filled with the magnetic field.IAXO: the International Axion Observatory -Pg 9 Sept 2014(PDF)

A Merry Christmas Sun Light



The sun emitted a significant solar flare, peaking at 7:24 p.m. EST on Dec. 19, 2014. NASA’s Solar Dynamics Observatory, which watches the sun constantly, captured an image of the event. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

To see how this event may affect Earth, please visit NOAA's Space Weather Prediction Center at http://spaceweather.gov, the U.S. government's official source for space weather forecasts, alerts, watches and warnings.

This flare is classified as an X1.8-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.

The Architecture of Matter?


Buckminsterfullerene-perspective-3D-balls

I cannot say for certain and I speculate. Bucky balls then bring to mind this architectural structure? Let me give you an example of a recent discovery. I have to wonder if Bucky was a Platonist at heart......with grand ideas? Perhaps you recognze some Platonist idea about perfection as if mathematically a Tegmarkan might have found some truth? Some absolute truth? Perhaps a Penrose truth (Quasicrystal and Information)?

 Aperiodic tilings serve as mathematical models for quasicrystals, physical solids that were discovered in 1982 by Dan Shechtman[3] who subsequently won the Nobel prize in 2011.[4] However, the specific local structure of these materials is still poorly understood .Aperiodic tilings -


 While one starts with a single point of entry......the whole process from another perspective is encapsulated. So you might work from the hydrogen spectrum as a start with the assumption, that this process in itself is enclosed.

 
 The future lies in encapsulating all electromagnetic forces under the auspice and enclosed within the understanding of gravity?

At the same time one might understand the complexity of the issue?

 By now it is known theoretically that quantum angular momentum of any kind has a discrete spectrum, which is sometimes imprecisely expressed as "angular momentum is quantized".Stern–Gerlach experiment -

So possibly a Photon polarization principle inherent in a quantum description of the wave and such a principle inherent in the use of photosynthesis to describe a property not just of the capability of using sun light, but of understanding this principle biologically in human beings? I actually have a example of this use theoretically as a product. Maybe Elon Musk might like to use it?


Photonic molecules are a synthetic form of matter in which photons bind together to form "molecules". According to Mikhail Lukin, individual (massless) photons "interact with each other so strongly that they act as though they have mass". The effect is analogous to refraction. The light enters another medium, transferring part of its energy to the medium. Inside the medium, it exists as coupled light and matter, but it exits as light.[1]


While I would like to make it easy for you, I can only leave a title for your examination. "The Nobel Prize in Physics 1914 Max von Laue." Yes, but if it is understood that some correlate process can be understood from "a fundamental position," as to the architecture of matter, what would this light have to say about the component structuralism of the information we are missing?


The idea is not new. From a science fiction point of view, StarTrek had these units that when you were hungry or wanted a drink you would have this object materialize in a microwave type oven? Not the transporter.

So, you have this 3d printer accessing all information about the structure and access to the building blocks of all matter in energy, funneled through this replicator.

 When Bucky was waving his arm between the earth and the moon.....did he know about the three body problem, or how to look at the space between these bodies in another way. If people think this is not real, then you will have to tell those who use celestial mechanics that they are using their satellite trajectories all wrong.

 Ephemeralization, a term coined by R. Buckminster Fuller, is the ability of technological advancement to do "more and more with less and less until eventually you can do everything with nothing".[1] Fuller's vision was that ephemeralization will result in ever-increasing standards of living for an ever-growing population despite finite resources.

 Exactly. So it was not just "hand waving" Buckminister Fuller is alluding too, but some actual understanding to "more is less?" One applies the principle then? See? I am using your informational video to explain.

 To do more with less, it has to be understood that distance crossed needs minimum usage of fuel to project the satellite over a great distance. So they use "momentum" to swing satellites forward?

 This is a list of various types of equilibrium, the condition of a system in which all competing influences are balanced. List of types of equilibrium -

Quantum physics says that particles can behave like waves, and vice versa. Research published in Nature Communications shows that this 'wave-particle duality' is simply the quantum uncertainty principle in disguise.
An international team of researchers has proved that two peculiar features of the quantum world – previously considered distinct – are different manifestations of the same thing. The result is published 19 December in Nature Communications.

Patrick Coles, Jedrzej Kaniewski, and Stephanie Wehner made the breakthrough while at the Centre for Quantum Technologies at the National University of Singapore. They found that 'wave-particle duality' is simply the quantum 'uncertainty principle' in disguise, reducing two mysteries to one.

"The connection between uncertainty and wave-particle duality comes out very naturally when you consider them as questions about what information you can gain about a system. Our result highlights the power of thinking about physics from the perspective of information," says Wehner, who is now an Associate Professor at QuTech at the Delft University of Technology in the Netherlands.

The discovery deepens our understanding of quantum physics and could prompt ideas for new applications of wave-particle duality................... SEE : CQT (Centre for Quantum Technologies)-Two quantum mysteries merged into one
