 | Using the Janus laser at LLNL and the Omega laser at the University of Rochester, Livermore scientists and Rochester and UC Berkeley colleagues showed that when shock waves are applied to diamond with powerful lasers, it can support almost a million times atmospheric pressure before being crushed. ...> Full Article |
 | In an advance that might interest Q-Branch NIST and partners from industry and academia have designed and tested experimental antennas that are highly efficient and yet a fraction of the size of standard antenna systems with comparable properties. ...> Full Article |
 | Researchers at the Joint Quantum Institute can speed up photons to seemingly faster-than-light speeds through a stack of materials by adding a single, strategically placed layer. ...> Full Article |
Brandeis University announced today a $1 million, three-year award from the W.M. Keck Foundation to help support experimental research into a new category of materials known as active matter. The project seeks to elucidate the behavior of active matter at length scales ranging from the microscopic to the macroscopic.

 | The remarkable feat of tying light in knots has been achieved by a team of physicists working at the universities of Bristol, Glasgow and Southampton, UK, reports a paper in Nature Physics this week.
Understanding how to control light in this way has important implications for laser technology used in wide a range of industries.

 | Is there anybody out there? In Alejandro Jenkins' case, the question refers not to whether life exists elsewhere in the universe, but whether it exists in other universes outside of our own. ...> Full Article |
Northwestern University researchers have developed compact, mid-infrared laser diodes that generate more light than heat -- a breakthroughs in quantum cascade laser efficiency.

 | Physicists have finally managed to demonstrate quantum entanglement of spatially separated electrons in solid state circuitry. ...> Full Article |
In an important first for a promising new technology, scientists have used a quantum computer to calculate the precise energy of molecular hydrogen. This groundbreaking approach to molecular simulations could have profound implications not just for quantum chemistry, but also for a range of fields from cryptography to materials science.

 | Physicists may see data by late summer from a prototype for a $278 million NOvA neutrino experiment that can yield clues to the universe's mysteries. Construction is underway on a 220-ton "integration prototype" detector and a larger 14,000-ton detector, a project of Fermilab and University of Minnesota. About 40 scientists will fine-tune design Jan. 8-10 at Southern Methodist University in Dallas, their first meeting since the US Department of Energy's October approval of "full construction start." ...> Full Article |
New experiments on a recently discovered class of iron-based superconductors suggest that the ability of their electrons to conduct electricity without resistance is directly connected with the magnetic properties of those electrons. Appearing in the Jan. 8 issue of Physical Review Letters, the results by U.S. and Chinese physicists bolster theories that high-temperature superconductivity in materials called "iron pnictides" arises from quantum magnetic fluctuations.

Astrophysicists using supercomputers to simulate the Big Bang have a new mathematical tool to model the early universe, says mathematician Daniel Reynolds at Southern Methodist University, Dallas. Reynolds and a team of astrophysicists built a computer model of the "Dark Ages." The model -- successfully tested on two supercomputers -- tightly couples physical processes present during cosmic reionization. Resulting simulations when scientists model various scenarios are highly accurate, numerically stable and computationally scalable to the largest supercomputers.

 | Iowa State University physicists are starting to see real data from the Large Hadron Collider, the planet's biggest science experiment. But, said Chunhui Chen, an Iowa State assistant professor of physics and astronomy, it will still take years of study before the collider produces new, Nobel-winning physics. ...> Full Article |
Researchers from the German Helmholtz-Zentrum Berlin f�r Materialien und Energie, in cooperation with colleagues from Oxford and Bristol Universities, as well as the Rutherford Appleton Laboratory, UK, have for the first time observed a nanoscale symmetry hidden in solid state matter. They have measured the signatures of a symmetry showing the same attributes as the golden ratio famous from art and architecture. The research team is publishing these findings in Science Jan. 8.

 | Researchers of the Institute for Quantum Optics and Quantum Informationin Innsbruck, Austria, used a calcium ion to simulate a relativistic quantum particle, demonstrating a phenomenon that has not been directly observable so far: the Zitterbewegung. They have published their findings in the current issue of the journal Nature. ...> Full Article |
