| Research Abstract |
Microscopic mechanisms of photo-induced phenomena and photo-induced phase transition in correlated electron systems with multi-degrees of freedom, e. g. spin and orbital, are revealed. In particular, photo-induced real-time dynamics in spin order, orbital order and spin-states (high spin/low spin)are analyzed by utilizing the analytical and numerical methods. Obtained results are applied to interpretations for the recent experimental data.
