Density Matrix Renormalization Group Study of Relaxation Dynamics in Strongly Correlated Electron systems

光致相变作为一种新的物质功能，受到了广泛的关注。特别是对铜酸盐、锰酸盐和钴酸盐等过渡金属氧化物进行了各种实验。在实验的激励下，我们构建了转换背后的基本概念。我们研究了自旋、电荷、轨道和声子自由度之间的耦合和分离，并研究了脉冲激光照射氧化物后这些量子度如何影响弛豫动力学。

Photoinduced phase transitions are attracted much attention as new functionalities of matter. In particular, various experiments have been done for transition metal oxides such as cuprates, manganites, and cobaltites. Motivated by the experiments, we have constructed the fundamental concepts behind the transitions. We have examined coupling and separation among spin, charge, orbital, and phonon degrees of freedom, and have also examined how these quantum degrees affect relaxation dynamics after pulse laser irradiation to the oxides.
