| Research Abstract |
Strongly correlated electron system, e.g., Hi Tc cuprates, organic compounds, are considered as next generation materials for device applications. In this research, I studied their nonequilibrium dynamics induced by electric fields and lasers theoretically. In addition, I have studied the spin dynamics also generated in these materials in strong external fields. I have, with my collaborators, extended the dynamical mean field theory to nonequilibrium, in order to pursue this goal. The results have been described in 9 original papers (1 is a review article), and 1 Japanese article.
