Theoretical study of thermoelectric response in time-reversal-symmetry breaking system

在强关联电子系统中，时间反演对称性破缺经常发生。铁磁态就是一个例子。本项目研究了强关联电子系统对外部扰动的响应。本文研究的主要问题是：（1）量子电子-经典自旋杂化系统的激发和弛豫的实时动力学。ii）由于强相关性，热功率的非单调温度依赖性。（3）超导体/磁体/超导体结理论。iv）强关联电子系统中磁性杂质的影响。

In the strongly correlated electron systems, the time-reversal-symmetry breaking often occurs. The ferromagnetic state is an example. In this project, the response of the strongly correlated electron systems to external disturbance has been studied. The main topics examined here are : i) Real-time dynamics of the excitation and relaxation of the quantum electron-classical spin hybrid system. ii) Non-monotonic temperature dependence in themopower due to strong correlation. iii) Theory of superconductor/magnet/superconductor junction. iv) Effect of magnetic impurity in strongly correlated electron systems.
