Ozawa Group

Welcome to Ozawa group at Advanced Institute for Materials Research (AIMR) at Tohoku University!
From April 2026, we will hold an additional group at RIKEN iTHEMS!
We are a theoretical physics research group, studying an intersection between condensed matter physics and atomic, molecular, and optical physics.
