| Research Abstract |
The interplay between the relativistic effects and the electron-electron interaction has been studied theoretically for the wide range of systems including topological insulators, semiconductors, and superconductors. Various physical properties such as transport, optical and magnetic properties in these systems were clarified. In addition, the dynamical processes of strongly interacting electrons when irradiated by light have been studied by quantum simulation revealing the fundamental mechanism of solar cell action in correlated electronic systems.
