About Us

Welcome to the homepage of Non-Equilibrium Working group (NEW) at RIKEN iTHEMS !

We are studying non-equilibrium physical phenomena in various energy scales/systems from an interdiciplinary point of view, since July 2021. Currently, we are working on (but not limited to) [A] Physics under strong fields, [B] Transport phenomena, and [C] Geometry and mathematical physics.
