Entanglement between a movable mirror and a cavity field with an atomic medium

Abstract

Abstract: A scheme to generate entanglement in a cavity optomechanical system filled with atomic medium is proposed. If the coupling between the cavity field and the atom medium is suitable, then the results show entanglement between the cavity and movable mirror, between the mirror and the atom, as well as between the cavity mode and the atom. Furthermore, the paper give number results by employing logarithmic negativity to quantity the entanglement including the cavity losses.

Key words: quantum optics, optomechanical system, atomic medium, Hamiltonian, entanglement
