Keywords:optical physics, correlated electron system, Magnetism

Photocontrol of electronic and lattice structures in solids have been developed in recent years. In this talk, I will introduce the non-equilibrium dynamics in many body system induced by photoirradiation. In paticular, I will talk about 1) photoinduced ferromagnetic-antiferromagnetic transition, 2) high-harmonic generation in correlated electron systems, and 3) photoirradiation effects in excitonic insulating system.
