Enhanced Entanglement Between Two Mechanical Resonators in Two Optomechanical Cavities with an Atomic Medium

摘要

We propose a theoretical method to enhance the entanglement between two mechanical resonators in two optomechanical cavities, which are coupled by the photon-hopping process, and each opto-mechanical cavity are consisted of a Fabry-Perot cavity and a mechanical oscillator by applying N atomic medium. We explore the effect of the entanglement between two mechanical oscillators with two atomic mediums and without them, respectively. The results show that the introduction of atoms can effectively increase the entanglement between the two oscillator modes.
