Potentially Harder Tests Needed for Quantifying Quantum Speedup

Texas A&M University physicist Helmut G. Katzgraber's research takes him to the crossroads of physics, computer science, quantum information theory and statistical mechanics. For more than a decade, he has been pushing the frontiers of computational physics to study hard optimization problems and disordered materials, applying his expertise to problems in the fascinating and fast-evolving field of quantum computing.

Ferromagnetism Switching Inspires Future Applications in Low-Power Spintronics

Scientists from Paris, Newcastle and Helmholtz-Zentrum Berlin have been able to switch on and off robust ferromagnetism close to room temperature by using low electric fields. Their results are inspiring for future applications in low-power spintronics, for instance, in fast, efficient and nonvolatile data storage technologies.

Researchers Study How Spin-Orbit Interaction Causes Anti-Parallel Spin States to Interact

In a recent publication B. Slomski and co-workers have been able to follow how spin-orbit interaction causes anti-prallel spin states to interact. The resulting spin flip yields an unexpected spin texture.

Swift's Ultraviolet/Optical Telescope Captures SN 2014J Supernova

An exceptionally close stellar explosion discovered on Jan. 21 has become the focus of observatories around and above the globe, including several NASA spacecraft. The blast, designated SN 2014J, occurred in the galaxy M82 and lies only about 12 million light-years away. This makes it the nearest optical supernova in two decades and potentially the closest type Ia supernova to occur during the life of currently operating space missions.

ORNL Research Could Lead to Better Superconductors

Nearly 30 years after the discovery of high-temperature superconductivity, many questions remain, but an Oak Ridge National Laboratory team is providing insight that could lead to better superconductors.

Novel Nanoscale Sensitive Quantum Measurement Device Operates at Wider Range of Temperatures

Nanoscale Superconducting QUantum Interference Devices (nanoSQUIDs) are potentially the most sensitive measurement devices in the world. They detect changes in an electromagnetic property known as magnetic flux, which means they can be used to detect single photons or to characterise the tiny quantum oscillations in nano-electromechanical systems (NEMS).

Intermittent Emissions of Water Vapor Discovered on Ceres Asteroid

An international team, including researchers from CNRS and the Paris Observatory at LESIA (Observatoire de Paris/CNRS/Université Pierre et Marie Curie/Université Paris-Diderot) and at IMCEE (Observatoire de Paris/CNRS/Université Pierre et Marie Curie/Université Lille 1), has discovered intermittent emissions of water vapor on Ceres, the largest of the asteroids, using the Herschel space telescope. These findings are published in the journal Nature dated 23 January 2014.
