Ground state cooling of an optomechanical resonator with double quantum interference processes*

Abstract

We present a cooling scheme with a tripod configuration atomic ensemble trapped in an optomechanical cavity. With the employment of two different quantum interference processes, our scheme illustrates that it is possible to cool a resonator to its ground state in the strong cavity–atom coupling regime. Moreover, with the assistance of one additional energy level, our scheme takes a larger cooling rate to realize the ground state cooling. In addition, this scheme is a feasible candidate for experimental applications.

Tunable phonon–atom interaction in a hybrid optomechanical system

“…Hybrid optomechanical systems, which integrate the advantages of several systems, have become a field of interest. [34][35][36][37][38][39] In this paper, we theoretically study a hybrid optomechanical system consisting of a neutral atom and a nanoparticle levitated in an optical cavity (see Fig. 1).…”
