RIKEN ECL Unit Leader: Rina Tazai (D.Sc)
Research Summary
Our unit conducts theoretical research on strongly correlated electron systems in solid-state materials such as superconductors and magnets. Condensed matter physics has historically advanced through close collaboration between theory and experiment. With recent progress in high-precision experimental techniques and faster computational methods, previously inaccessible phenomena are now being uncovered. Starting from microscopic theoretical models that describe individual electron behavior, our aim is to propose novel electronic phases, quantum phase transitions, and transport phenomena, thereby contributing to the deeper understanding of condensed matter systems and bridging theory with experiment.
