Nonlinear and nonequilibrium states in strongly correlated systems studied by nonequilibrium dynamical mean field theory

强相关电子系统，如高温铜酸盐，有机化合物，被认为是下一代器件应用的材料。在本研究中，我从理论上研究了它们在电场和激光诱导下的非平衡动力学。此外，我还研究了这些材料在强外场下产生的自旋动力学。为了实现这一目标，我和我的合作者将动力学平均场理论扩展到非平衡态。结果已在9篇原创论文（1篇综述文章）和1篇日文文章中描述。

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.
