Research Shows How Heat is Converted to Spin Current in Magnetic Superconductors

Physicists have shown how heat can be exploited for controlling magnetic properties of matter. The finding helps in the development of more efficient mass memories. The result was published yesterday in Physical Review Letters. The international research group behind the breakthrough included Finnish researchers from the University of Jyväskylä and Aalto University.

Inelastic Neutron Scattering Experiments Reveal Coexistence of Superconductivity and Magnetism

Inelastic neutron scattering experiments on a copper-oxide superconductor reveal nearly static, spatially modulated magnetism. Because static magnetism and superconductivity do not like to coexist in the same material, the superconducting wave function is also likely modulated in space and phase-shifted to minimize overlap, consistent with recent theory.

New Mathematical Proof Reveals a Much Tighter Limit on How Fast Quantum Information Can Propagate

If you’re designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but JQI physicists have narrowed the theoretical limits for where that “speed limit” is. The work implies that quantum processors will work more slowly than some research has suggested.

Mathematicians Develop New Method that Simplifies Big Data Using Ideas from Quantum Theory

Analysing the large volumes of data gathered by modern businesses and public services is problematic. Traditionally, relationships between the different parts of a network have been represented as simple links, regardless of how many ways they can actually interact, potentially loosing precious information.

Entangled Photons Cast a New Light on Quantum Cause and Effect

Does taking a drug and then getting better mean that the drug made you better? Did that tax cut really stimulate the economy or did it recover on its own? The problem of answering such questions – of inferring causal relationships from correlations – reaches across the sciences, and beyond.

AAS/SPD and AGU/SPA to Meet in Indiana for First Triennial Earth-Sun Summit

The American Astronomical Society's Solar Physics Division (AAS/SPD) and the American Geophysical Union's Space Physics and Aeronomy Section (AGU/SPA) will meet together at the Westin Indianapolis in Indiana for the first Triennial Earth-Sun Summit (TESS), 26-30 April 2015.

Some Galaxies Can Be Thrown Away From Their Host Clusters

Astronomers think, that there are dozens of billions undetectable free floating planets that straggle along our Milky Way galaxy, being not gravitationally bound to any star.

Hubble's 25th Anniversary Celebrated with Vibrant Image of Westerlund 2 Star Cluster

The glittering tapestry of young stars flaring to life in this new NASA/ESA Hubble Space Telescope image aptly resembles an exploding shell in a fireworks display. This vibrant image of the star cluster Westerlund 2 has been released to celebrate Hubble's 25th year in orbit and a quarter of a century of new discoveries, stunning images and outstanding science.

Quantum Correlated Light Beams Help Overcome Fundamental Detection Limit of Microcantilever-Based Sensors

Thermal imaging, microscopy and ultra-trace sensing could take a quantum leap with a technique developed by researchers at the Department of Energy’s Oak Ridge National Laboratory.

Astronomers Spot 11 Galaxies Exiled From Their Clusters

We know of about two dozen runaway stars, and have even found one runaway star cluster escaping its galaxy forever. Now, astronomers have spotted 11 runaway galaxies that have been flung out of their homes to wander the void of intergalactic space.

Physics Framework Underlying Unexpected Metal-to-Insulator-to-Metal Transitions

New work from Carnegie’s Russell Hemley and Ivan Naumov hones in on the physics underlying the recently discovered fact that some metals stop being metallic under pressure. Their work is published in Physical Review Letters.

Close Investigation of Two Very Different, Distant Dwarf Planets

The solar system is teeming with tiny rocks – but officially there are only five dwarfs: Ceres, Eris, Haumea, Makemake and Pluto. While the Dawn space probe is currently exploring Ceres, the New Horizons mission will hurtle past big brother Pluto on 14 July and record data and images of this faraway world en passant. The researchers will thus have a chance to more closely investigate two very different, distant dwarf planets.

Spin Phenomena Interdisciplinary Center Opens at Johannes Gutenberg University Mainz

Johannes Gutenberg University Mainz (JGU) today officially opened its new Spin Phenomena Interdisciplinary Center (SPICE), which will facilitate interactions between the many diverse fields that study spin-related phenomena – at a level that each field could not achieve on its own.

Researchers Await First Light of ESPRESSO Spectrograph on ESO's Very Large Telescope

The exoplanet 51 Pegasi b [1] lies some 50 light-years from Earth in the constellation of Pegasus. It was discovered in 1995 and will forever be remembered as the first confirmed exoplanet to be found orbiting an ordinary star like the Sun [2]. It is also regarded as the archetypal hot Jupiter -- a class of planets now known to be relatively commonplace, which are similar in size and mass to Jupiter, but orbit much closer to their parent stars.
