Leiden physicists image lumpy superconductor

High-temperature superconductivity is one of the big mysteries in physics. Milan Allan's research group used a Josephson Scanning Tunneling Microscope to image spatial variations of superconducting particles for the first ...

A sound idea: A step towards quantum computing

A team at the University of Tsukuba studied a novel process for creating coherent lattice waves inside silicon crystals using ultrashort laser pulses. Using theoretical calculations combined with experimental results that ...

Researchers modify magnetic behavior of exotic materials

People are not the only ones to be occasionally frustrated. Some crystals also show frustrations. They do so whenever their elementary magnets, the magnetic spins, cannot align properly. Cesium copper chloride (Cs2CuCl4) ...

How to freeze heat conduction

Physicists have discovered a new effect, which makes it possible to create excellent thermal insulators which conduct electricity. Such materials can be used to convert waste heat into electrical energy.

New insights into magnetic quantum effects in solids

Using a new computational method, an international collaboration has succeeded for the first time in systematically investigating magnetic quantum effects in the well-known 3-D pyrochlore Heisenberg model. The surprising ...
