Data Erased By Magnetic Monopoles
2013-05-31 12:38:36

Technische Universitaet Muenchen A physical particle postulated 80 years ago, could provide a decisive step toward the realization of novel, highly efficient data storage devices. Scientists at the Technische Universitaet Muenchen (TUM), the Technische Universitaet Dresden and the University of Cologne found that with magnetic monopoles in magnetic vortices, called skyrmions, information can be written and erased. Iron filings strewn on a sheet of paper trace the field lines of a bar...

Observing Competition In The Quantum World

University of Innsbruck "When water boils, its molecules are released as vapor. We call this change of the physical state of matter a phase transition," explains Sebastian Diehl from the Institute of Theoretical Physics at the University of Innsbruck. Together with his colleagues from the Institute for Experimental Physics and the theorist Markus Mueller from the Complutense University of Madrid, he studied the transition between two quantum mechanical orders in a way never before...

Pear Shaped Atomic Nuclei
2013-05-09 11:28:49

Brett Smith for redOrbit.com - Your Universe Online According to a study in the journal Nature, a team of international scientists has found the first ever direct evidence of pear-shaped atomic nuclei. Bizarre pear-shaped nuclei could be the key to understanding one of the great mysteries of the universe: the reason for the Big Bang´s creation of a massive imbalance between matter and antimatter. "If equal amounts of matter and antimatter were created at the Big Bang, everything...

First Direct Evidence Of How Antimatter Interacts With Gravity
2013-04-30 10:11:53

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online All fundamental matter in the Universe — protons, electrons, etc. — has counterparts known as antimatter. In most ways, antimatter simply mirrors regular matter. For instance, the antimatter counterpart to the electron is the positron, a particle of the same mass of the electron, but possessing the opposite charge and opposite spin. When normal matter encounters its antimatter counterpart, the pair will...

An international team of scientists has shed new light on a fundamental area of physics which could have important implications for future electronic devices and the transfer of information at the quantum level. The electrical currents currently used to power electronic devices are generated by a flow of charges. However, emerging quantum technologies such as spin-electronics, make use of both charge and another intrinsic property of electrons — their spin — to transfer and...

Speed Of Light May Not Be Fixed After All
2013-03-26 05:03:34

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online When we talk about the vacuum of space, we imagine a complete lack of matter — a cold void, dark, and absent of all energy. Over the last century, however, physicists have come to realize that the emptiness of space is anything by empty. On the macro scale, the vacuum of empty space may appear to lack matter and energy as we normally think of it. But when we look closely, and begin to examine the quantum...

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...

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...
