“Theoretical developments in nonequilibrium electron systems: strongly correlated system and Floquet topological phase transition”
Sample program of real time dynamical mean field theory
Research
interest: (Theoretical Condensed Matter Physics)
I am interested in non-equilibrium phase transitions in strongly correlated
electron systems (SCES)
and other exotic properties (e.g., transport).
