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

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. [More]
Inelastic Neutron Scattering Experiments Reveal Coexistence of Superconductivity and Magnetism

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

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. [More]
Entangled Photons Cast a New Light on Quantum Cause and Effect

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

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. [More]
Some Galaxies Can Be Thrown Away From Their Host Clusters

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. [More]
Hubble's 25th Anniversary Celebrated with Vibrant Image of Westerlund 2 Star Cluster

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.

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. [More]
