| Research Abstract |
There are many materials which show so-called photoinduced phase transitions, macroscopic changes of electronic states induced by photoirradiation. In this study, we theoretically clarify physical properties of photoexcited states generated immediately after the photoirradiation and the subsequent dynamics. In particular, we carry out numerical analysis of the photoexcited states and dynamical properties of one-dimensional (1D) electron-lattice systems corresponding to quasi-1D organic compounds and a multi-band Hubbard model which is a minimal model of transition metal oxides.
