| Research Abstract |
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.
