Quantum Chaotic Behavior In Ultracold Gas Discovered
2014-03-13 15:02:29

University of Innsbruck The team of Francesca Ferlaino, Institute for Experimental Physics of the University of Innsbruck, Austria, has experimentally shown chaotic behavior of particles in a quantum gas. "For the first time we have been able to observe quantum chaos in the scattering behavior of ultracold atoms," says an excited Ferlaino. The physicists used random matrix theory to confirm their results, thus asserting the universal character of this statistical theory. Nobel laureate...

Gas giant Jupiter
2014-03-12 05:09:27

April Flowers for redOrbit.com - Your Universe Online An international team of researchers recently got a sneak peek deep into the lower atmospheric layers of gas giant planets such as Jupiter or Saturn using Deutsches Elektronen-Synchrotron's (DESY) X-ray laser FLASH. The team's observations, led by Dr. Ulf Zastrau of the University of Jena, demonstrate how liquid hydrogen becomes a plasma. The findings, published in Physical Review Letters, also provide information on the material's...

Van Allen Probes Helping To Refine Space Weather Computer Models
2014-03-10 07:45:30

redOrbit Staff & Wire Reports - Your Universe Online Data from the Van Allen Probes has been combined with a high-powered computer model to help researchers test and improve the forecast model to determine how the two giant near-Earth radiation belts they orbit can affect technology in space, NASA officials reported on Friday. The Van Allen radiation belts, which are teeming with rapidly-moving particles and a space weather system that varies in response to incoming solar particles...

Ultra Sensitive Detection Of Radio Waves Using Lasers
2014-03-05 14:30:33

University of Copenhagen - Niels Bohr Institute Radio waves are used for many measurements and applications, for example, in communication with mobile phones, MRI scans, scientific experiments and cosmic observations. But 'noise' in the detector of the measuring instrument limits how sensitive and precise the measurements can be. Now researchers at the Niels Bohr Institute have developed a new method where they can avoid noise by means of laser light and can therefore achieve extreme...

Researchers Demonstrate New Principle For Magnetic Recording

Johannes Gutenberg University Mainz The research group of Professor Jairo Sinova at the Institute of Physics at Johannes Gutenberg University Mainz (JGU), in collaboration with researchers from Prague, Cambridge, and Nottingham, have predicted and discovered a new physical phenomenon that allows to manipulate the state of a magnet by electric signals. Current technologies for writing, storing, and reading information are either charge-based or spin-based. Semiconductor flash or random...

Researchers Have Created A Stable Two-dimensional Electron Gas In Strontium Titanate
2014-03-04 08:12:15

Florian Aigner, Vienna University of Technology Usually, microelectronic devices are made of silicon or similar semiconductors. Recently, the electronic properties of metal oxides have become quite interesting. These materials are more complex, yet offer a broader range of possibilities to tune their properties. An important breakthrough has now been achieved at the Vienna University of Technology: a two dimensional electron gas was created in strontium titanate. In a thin layer just...

Auburn, MA (PRWEB) February 27, 2014 Vacuum Compatible and Non-Magnetic The new catalog covers a variety of novel actuators, stages and scanning systems, mostly based on the piezo effect. These ceramic drives are vacuum compatible and can also be manufactured in non-magnetic versions, important for...

Physicists Discover 'Quantum Droplet' In Semiconductor
2014-02-27 14:31:14

National Institute of Standards and Technology (NIST) JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle—a handful of smaller particles that briefly condense into a liquid-like droplet. Quasiparticles are composites of smaller particles that can be created inside solid materials and act together in a predictable way. A simple example is the exciton, a pairing, due to electrostatic forces, of an electron and a so-called...

Ion Beams Used To Create New Kinds Of Valves For Use In Spintronics
2014-02-19 10:26:38

Helmholtz-Zentrum Dresden-Rossendorf (HZDR) Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have tested a new approach to fabricating spin valves. Using ion beams, the researchers have succeeded in structuring an iron aluminium alloy in such a way as to subdivide the material into individually magnetizable regions at the nanometer scale. The prepared alloy is thus able to function as a spin valve, which is of great interest as a candidate component for use in spintronics....

The Cathode Ray Tube, which has internal or external means to accelerate and deflect electron beams, is a vacuum tube containing an electron gun and a fluorescent screen. The electron beams that are deflected are used to create images in the form of light emitted from the fluorescent screen. The CRT works by using an evacuated glass envelope which is large, deep, heavy, and relatively fragile. Ferdinand Braun is credited with the first CRT in 1897. It can also be known as the Braun tube....

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...
