By Jennifer Marcus, UCLA Physicists at UCLA set out to design a better transistor and ended up discovering a new way to think about the structure of space. Space is usually considered infinitely divisible "” given any two positions, there is always a position halfway between. But in a recent study aimed at developing ultra-fast transistors using graphene, researchers from the UCLA Department of Physics and Astronomy and the California NanoSystems Institute show that dividing space into...

Technique suggests an avenue for creating new kinds of superconductivity Physicists at the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland-College Park, have for the first time caused a gas of atoms to exhibit an important quantum phenomenon known as spin-orbit coupling. Their technique opens new possibilities for studying and better understanding fundamental physics and has potential applications to...

The fabric of space-time around spinning black holes should impart a "twist" in the property of light called orbital angular momentum. This momentum which could be detected here on Earth, the researchers say, may provide the first unique signature of black holes, reports the journal Nature Physics. Light particles , or photons, carry two kinds of momentum but only one of them is familiar. "If we take the Earth as an example, it spins around its own axis in about 24 hours - that is its spin...

Scientists from the Kavli Institute of Nanoscience at Delft University of Technology and Eindhoven University of Technology have succeeded in controlling the building blocks of a future super-fast quantum computer. They are now able to manipulate these building blocks (qubits) with electrical rather than magnetic fields, as has been the common practice up till now. They have also been able to embed these qubits into semiconductor nanowires. The scientists' findings have been published in the...

Physicists read data after storing them in atomic nuclei for 112 seconds University of Utah physicists stored information for 112 seconds in what may become the world's tiniest computer memory: magnetic "spins" in the centers or nuclei of atoms. Then the physicists retrieved and read the data electronically "“ a big step toward using the new kind of memory for both faster conventional and superfast "quantum" computers. "The length of spin memory we observed is more than adequate to...

A new material with a split personality -- part superconductor, part metal -- has been observed by a Princeton University-led research team. The discovery may have implications for the development of next-generation electronics that could transform the way information is stored and processed. The new material -- a crystal called a topological superconductor -- has two electronic identities at once. At very low temperatures, the interior of the crystal behaves like a normal superconductor,...

Braided anyons could lead to more robust quantum computing When confined to a 2-dimensional sheet, some exotic particle-like structures known as anyons appear to entwine in ways that could lead to robust quantum computing schemes, according to research appearing in the November 1 issue of the journal Physical Review B. The physicists at Bell Laboratories who performed the research are hopeful the anyons can be induced to follow paths that twist into braids that would be much more resistant to...

At the Large Hadron Collider at CERN protons crash into each other at incredibly high energies in order to 'smash' the protons and to study the elementary particles of nature "“ including quarks. Quarks are found in each proton and are bound together by forces which cause all other known forces of nature to fade. To understand the effects of these strong forces between the quarks is one of the greatest challenges in modern particle physics. New theoretical results from the Niels Bohr...

The integration of single-spin magnetoelectronics into standard silicon technology may soon be possible, if experiments confirm a new theoretical prediction by physicists at the Naval Research Laboratory and the University of Wisconsin-Madison. The researchers predict that a family of well-known silicon surfaces, stabilized by small amounts of gold atoms, is intrinsically magnetic despite having no magnetic elements. None of these surfaces has yet been investigated experimentally for...

Communications in Mathematical Physics is a peer-reviewed academic journal published by Springer. The founding editor-in-chief was Rudolf Haag, who established the journal in 1965 with the help of Res Jost. Haag headed the journal for the next eight years, and was succeeded by Klaus Hepp, followed by James Glimm, Arthur Jaffe and the Michael Aizenman, who took over in 2000. The journal publishes papers in all fields of mathematical physics, but focuses particularly in analysis related to...
