Abstract

Recently [J.Q. Liao, C.K. Law, Phys. Rev. A. 83, 033820 (2011)] theoretically investigated the possibility of generating the quadrature-squeezed states of a moving mirror in a Fabry-Perot cavity. But, the generation of squeezing is limited by the thermal noise of the environment. We propose an approach to lessen such limitations by adding atoms into the cavity. We demonstrate that such a system can lead to a lager squeezing than the case without atoms.
