Abstract
Optomechanical dynamics induced by radiation pressure is investigated in Fabry-Perot cavity optomechanical system. We start from the Hamiltonian of the optomechanical system at the condition of detuned to study the quantum phenomenon in the optomechanical cavity. A scattering matrix formulation which demonstrates the converting photons to phonons in an efficient and reversible manner is introduced. This provides a feasible route towards quantum state transfer between optical photons and micromechanical resonators. The phonon-photon transfer maybe suggests a possible quantum optical device. Meanwhile, two methods which are quantum Langevin approximate and a master-equation approach are considered to investigate the ground state cooling, and we compare the two methods. Our results showed which scheme is practical under what conditions.
