Theoretical developments in nonequilibrium electron systems: strongly correlated system and Floquet topological phase transition

Lecture 1, 2, 3, 4

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).
