Draw out of the predicted interatomic force

Liquid Bi shows a peculiar dispersion of the acoustic mode, which is related to the Peierls distortion in the crystalline state. These results ("Anomalous dispersion of the acoustic mode in liquid Bi") will provide valuable inspiration to researchers developing new materials in the nanotechnology field. Fig.1: Momentum dependence of excitation energy....

Electrons that stick together, superconduct together

The discovery of a surprising feature of superconductivity in an unconventional superconductor by a RIKEN-led research team provides clues about the superconducting mechanism in this material and thus could aid the search for room-temperature superconductors ("Emergent loop-nodal s+--wave superconductivity in CeCu2Si2: Similarities to the iron-based...

Electrons take a phonon bath

In fundamental physics, it is relatively easy to describe the motion of a single moving particle, but it is much more challenging to develop a reliable theoretical description of a particle such as an electron moving in an environment where it interacts with many other particles. Now, Naoto Nagaosa and Andrey Mishchenko of the RIKEN Center for Emergent...
