Einstein's 134th Birthday
2013-03-14 14:34:12

Brett Smith for redOrbit.com - Your Universe Online Albert Einstein, almost unanimously considered the greatest physicist since Sir Isaac Newton, would have turned 134 today. His legacy can still be seen in modern society — in the revelations being made by physicists around the world and by his theories that they are still struggling to comprehend. "I am convinced that (God) does not play dice." Perhaps the most prominent contemporary example of Einstein´s legacy is...

In an article published in the PNAS scientific journal, researchers from Aalto University and the VTT Technical Research Centre of Finland showed experimentally that vacuum has properties not previously observed. According to the laws of quantum mechanics, it is a state with abundant potentials. Vacuum contains momentarily appearing and disappearing virtual pairs, which can be converted into detectable light particles. The researchers conducted a mirror experiment to show that by changing...

Quantum Spin Liquid Is A New State Of Magnetism
2012-12-21 09:38:33

redOrbit Staff & Wire Reports - Your Universe Online While experts had previously only confirmed the existence of two states of magnetism, experts from the Massachusetts Institute of Technology (MIT) report that they have been able to experimentally demonstrate the existence of a third kind. The MIT researchers have dubbed the new state a quantum spin liquid (QSL), and they describe their findings in this week's edition of the journal Nature. It joins ferromagnetism (the simple form...

Researchers Find Limit On CPT Violation From Gamma-Ray Bursts
2012-12-07 15:12:11

Lee Rannals for redOrbit.com — Your Universe Online Researchers wrote in the journal Physical Review Letters that they have found evidence of a strict limit on CPT violation from polarization of gamma-ray bursts. Photons produced by gamma-ray bursts travel billions of light years to reach the Earth. This makes them excellent probes of space-time structures on extremely small scales. Some quantum gravity theories predict that structures of space-time at extremely short...

New research has demonstrated a way to make bismuth electrons and nuclei work together as qubits in a quantum computer. The discovery, published in Nature Materials, takes us a key step further to creating practical quantum computing which could tackle complex programs that would otherwise take the lifetime of the universe to finish. The collaboration partners are based in the University of Warwick, UCL, ETH Zurich and the USA Sandia National Labs. Information on our normal computers...

A cornerstone of physics may require a rethink if findings at the National Institute of Standards and Technology (NIST) are confirmed. Recent experiments suggest that the most rigorous predictions based on the fundamental theory of electromagnetism–one of the four fundamental forces in the universe, and harnessed in all electronic devices–may not accurately account for the behavior of atoms in exotic, highly charged states. The theory in question is known as quantum...

SLAC National Accelerator Laboratory Time's quantum arrow has a preferred direction, new analysis shows Time marches relentlessly forward for you and me; watch a movie in reverse, and you´ll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse — a concept known as time reversal...

With headlines proclaiming the discovery of the Higgs boson–the so-called God particle–particle physics has captured the imagination of the world, particularly among those who dwell on the nature of the cosmos. But this is only one puzzle seemingly solved in a universe of mysteries. In a recent paper in Physical Review Letters, Dartmouth physicists delve into another enigmatic particle. Majorana is a name whose very mention evokes a veil of mystery. On one level, it refers to a...

Has The Higgs Boson Really Been Found?
2012-08-01 13:56:54

Brett Smith for redOrbit.com - Your Universe Online After years of theories and speculation, the Higgs boson particle discovery was announced on July 4, or was it? Several caveats swirled around the somewhat anti-climactic announcement, and almost a month later many scientists familiar with the CERN project are still reluctant to definitively say what they found was the so-called ℠God Particle´. A new report by the Atlas team working at the Large Hadron Collider that cited...

Communications in Mathematical Physics
2012-06-04 14:23:51

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...
