Spin Physics Theory Research Team
RIKEN Center for Emergent Matter Science
(Team Director: Gen Tatara)

Outline of Laboratory

Our aim is to explore novel spin-related effects with extremely high efficiency in condensed matter. We thus contribute to development of spintronics, a technology using spin as well as charging of electrons, and to realization of ultrafast and high-density information technology with low energy consumption. Our particular interest is at present in a strong quantum relativistic effect in solids, which is applicable to very strong magnets and efficient conversion of spin information to an electric signal. Our main method is a field theory.
