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.

理研iTHEMSの非平衡ワーキンググループ(NEW)のホームページへようこそ。 私たちは分野横断的な視点から非平衡物理を幅広く研究しています。
