Dynamical phase transition in Floquet optical bistable systems: An approach from finite-size quantum systems
Tatsuhiko Shirai, Synge Todo, Seiji Miyashita
We study a dynamical phase transition in optical bistable systems subject to a time-periodic driving field. The phase transition occurs in the structure of limit cycle as a functio…
