Device splits and recombines superconducting electron pairs

A device that can separate and recombine pairs of electrons may offer a way to study an unusual form of superconductivity, according to RIKEN physicists. This superconducting state would involve exotic particles called Majorana ...

Algorithm predicts the compositions of new materials

A machine-learning algorithm that can predict the compositions of trend-defying new materials has been developed by RIKEN chemists1. It will be useful for finding materials for applications where there is a trade-off between ...

The quantum spin Hall effect is a fundamental property of light

In a paper that crystalizes knowledge from a variety of experiments and theoretical developments, scientists from the RIKEN Center for Emergent Matter Science in Japan have demonstrated that the quantum spin Hall effect—an ...
