Outline of Final Research Achievements

There are many materials which shows photoinduced phenomena including photoinduced phase transitions, induced by photo irradiation. In this study, we theoreticaly investigate physical properties of quantum states emerging in the initial process of the photoexcitation. In particular, we analyze photoexcited states of various strongly correlated electron systems, ultrafast coherent-phonon generation and related transient Fano resonance in bulk semiconductors, laser-induced resonance states with long lifetime in semiconductor superlattices by using numerical techniques.
