Abstract: (1025 Views)
We proposed a fast ground-state optomechanical cooling methodfor a bad optomechanical system. A PT system consists of a gain cavity, whichis coupled to an optomechanical cavity. Also, a quarter-wave plate provideslinear mixing interaction between the optomechanical cavity and the thirdmode. Our proposed system improved the cooling rate by using two methods. The energy localization in the gain cavity and the destructive quantum interference are the important e_ects that enhance the cooling rate. Our most important achievement is that the optomechanical cavity is present in both the bad-cavity limit and the weak optomechanical coupling regime. These innovations can be attained by parameter management of the system.
