New Light on Superconductivity in Transition Metal Binary Alloys

Physicists from India have shed new light on a long-unanswered question related to superconductivity in so-called transition metal binary alloys. The team revealed that the local magnetic fluctuations, or spin fluctuations, an intrinsic property of Titanium-Vanadium (Ti-V) alloys, influence superconductivity in a way that is more widespread than previously thought.

New Results on Important Property of Higgs Particle

In a paper published in the journal Nature Physics today, the CMS experiment at CERN reports new results on an important property of the Higgs particle, whose discovery was announced by the ATLAS and CMS experiments on 4 July 2012. The CMS result follows preliminary results from both experiments, which both reported strong evidence for the fermionic decay late in 2013.

Non-Locality can be Detected in Many-Body Quantum Systems

Science has recently published a study carried out by researchers at ICFO in collaboration with the Institute for Nuclear Research, Hungarian Academy of Sciences, which demonstrates the capability of detecting non-locality in many-body quantum systems by constructing multipartite Bell inequalities involving only two-body correlations.

CERN Scientists Find Evidence for Direct Decay of the Higgs Boson into Fermions

For the first time, scientists from the CMS experiment on the Large Hadron Collider (LHC) at CERN have succeeded in finding evidence for the direct decay of the Higgs boson into fermions. Previously, the Higgs particle could only be detected through its decay into bosons. "This is a major step forwards," explains Professor Vincenzo Chiochia from the University of Zurich's Physics Institute, whose group was involved in analyzing the data.

DOE Extends Funding for Energy Frontier Research Center at Brookhaven National Lab

The U.S. Department of Energy (DOE) has announced an extension of funding totaling $14 million over four years for an Energy Frontier Research Center (EFRC) first established at DOE's Brookhaven National Laboratory in 2009. It is one of 32 EFRCs announced by U.S. Energy Secretary Ernest Moniz to accelerate the scientific breakthroughs needed to build the 21st-century energy economy.

Optical Steady Behavior Analyzed in GaAs Quantum Well Structure Driven by EPF

A new proposed scheme, by Wen-Xing Yang, from the Department of Physics, Southeast University, China, and colleagues, analyzed in detail the optical steady behavior in GaAs quantum well structure driven by an elliptically polarized field (EPF) in a unidirectional ring cavity.

Gas Stream Rapidly Flows Outward from NGC 5548 Galaxy's Supermassive Black Hole

An international team of astronomers, using data from several NASA and European Space Agency (ESA) space observatories, has discovered unexpected behavior from the supermassive black hole at the heart of the galaxy NGC 5548, located 244.6 million light-years from Earth. This behavior may provide new insights into how supermassive black holes interact with their host galaxies.
