RIKEN Center for Emergent Matter Science Quantum Matter Theory Research Team
Team Leader: Akira Furusaki (D.Sc.)
Research Summary

Quantum Matter Theory Research Team theoretically studies emergent quantum phenomena of strongly correlated electrons in transition metal oxides, molecular conductors, frustrated quantum magnets, and topological insulators and superconductors, etc. We construct effective models for interacting electrons in materials of interest and study their physical properties such as magnetism and transport using both analytical and numerical methods.
