Mechanical cooling in the bistable regime of a dissipative optomechanical cavity with a Kerr medium

In this paper, we study static bistability and mechanical cooling of a dissipative optomechanical cavity filled with Kerr medium. The system exhibits optical for wide input-power range the power threshold being greatly reduced, in contrast to case purely coupling. At bistable regime, membrane can be effectively cooled down few millikelvin from room temperature under unresolved sideband condition, where effective is nonmonotonic function intracavity intensity reaches its minimum near turning point upper stable branch. When cryogenics environment, at regime shows similar feature as case, but optimal appears monostable approaches ground state. Our results are interest further understanding systems, which have many applications nonclassical state preparations quantum information processing.
