Rice University researchers first to see superfluorescence from solid-state material In a flash, the world changed for Tim Noe — and for physicists who study what they call many-body problems. The Rice University graduate student was the first to see, in the summer of 2010, proof of a theory that solid-state materials are capable of producing an effect known as superfluorescence. That can only happen when "many bodies" — in this case, electron-hole pairs created in a...

Physicists Mimic Jupiter's Trojan Asteroids Inside Single Atom

[ Watch the Video ] Orbit of captured electron matches orbit of Jupiter's captured asteroids Rice University physicists have gone to extremes to prove that Isaac Newton's classical laws of motion can apply in the atomic world: They've built an accurate model of part of the solar system inside a single atom of potassium. In a new paper published this week in Physical Review Letters, Rice's team and collaborators at the Oak Ridge National Laboratory and the Vienna University of...

Researchers at the Niels Bohr Institute have combined two worlds — quantum physics and nano physics, and this has led to the discovery of a new method for laser cooling semiconductor membranes. Semiconductors are vital components in solar cells, LEDs and many other electronics, and the efficient cooling of components is important for future quantum computers and ultrasensitive sensors. The new cooling method works quite paradoxically by heating the material! Using lasers, researchers...

A report published this week indicates that a new, secure, high-speed computing technology based on quantum physics is compatible with “cloud computing” and could eventually revolutionize the world of computers as we currently understand it. Blind quantum computing, as it´s being called, exploits uncertainties in quantum physics to carry out ultra-fast computations. And according to an international team of researchers who published their work in this week´s issue of...

Physicists have developed the first conclusive test to better understand high-energy particles correlations. Researchers have devised a proposal for the first conclusive experimental test of a phenomenon known as ℠Bell´s nonlocality.´ This test is designed to reveal correlations that are stronger than any classical correlations, and do so between high-energy particles that do not consist of ordinary matter and light. These results are relevant to the so-called ℠CP...

Breakthrough in coordinating electrons advances goal of quantum computing An international team of researchers including scientists at Princeton University have achieved a 100-fold increase in the ability to maintain control the spins of electrons in a solid material, a key step in the development of ultrafast quantum computers. Until recently, the best attempts at such control lasted for only a fraction of a second. But researchers Stephen Lyon and Alexei Tyryshkin have found a way to...

Measurements at the Vienna University of Technology deepen our understanding of quantum uncertainty Heisenberg's Uncertainty principle is arguably one of the most famous foundations of quantum physics. It says that not all properties of a quantum particle can be measured with unlimited accuracy. Until now, this has often been justified by the notion that every measurement necessarily has to disturb the quantum particle, which distorts the results of any further measurements. This, however,...

Study represents step toward unified theory for quantum phase transformation New evidence this week supports a theory developed five years ago at Rice University to explain the electrical properties of several classes of materials -- including unconventional superconductors -- that have long vexed physicists. The findings in this week's issue of Nature Materials uphold a theory first offered in 2006 by physicist Qimiao Si, Rice's Harry C. and Olga K. Wiess Professor of Physics and...

Miguel A. Cazalilla, a scientist at the CFM (a joint CSIC-UPV/EHU center) and the Donostia International Physics Center (DIPC), together with other four colleagues from various institutions in Europe and the United States, was recently invited to write a review article that has been just published in the prestigious journal Reviews of Modern Physics of the American Physical Society, where only leading scientists in their field of physics are invited to contribute. The article, "One...

Physicists at Harvard University have realized a new way to cool synthetic materials by employing a quantum algorithm to remove excess energy. The research, published this week in the journal Nature, is the first application of such an "algorithmic cooling" technique to ultra-cold atomic gases, opening new possibilities from materials science to quantum computation. "Ultracold atoms are the coldest objects in the known universe," explains senior author Markus Greiner, associate professor...

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Open Systems & Information Dynamics (OSID) is journal published by World Scientific. The aim of the Journal is to promote interdisciplinary research in mathematics, physics, engineering and life sciences centered around the issues of broadly understood information processing, storage and transmission, in both quantum and classical settings. Our special interest lies in the information-theoretic approach to phenomena dealing with dynamics and thermodynamics, control, communication,...

Niels Henrik David Bohr (October 7, 1885 - November 18, 1962) was a Danish physicist. He made essential contributions to understanding atom structure and quantum mechanics. Born in Copenhagen, Denmark to Christian Bohr and Ellen Adler, Bohr got his doctorate at Copenhagen University in 1911. He then studied under Ernest Rutherford in Manchester, England. Based on Rutherford's theories, Bohr published his Bohr model about atom structure in 1913, introducing the theory of electrons...

Multiverse -- The term Multiverse was invented in December 1960, by Andy Nimmo, then vice chairman of the British Interplanetary Society, Scottish Branch, for a talk on the Everett many-worlds interpretation of quantum physics which had been published in 1957, to the branch. This was given in February 1961, and the word with its original definition, "an apparent universe, a multiplicity of which, go to make up the whole universe" was then first used. This was because the then dictionary...
