Abstract: | We theoretically investigate the stationary entanglement of a optomechanical system with an additional Kerr medium in the cavity.There are two kinds of interactions in the system,photon-mirror interaction and photon-photon interaction.The optomechanical entanglement created by the former interaction can be effectively controlled by the latter one.We find that the optomechanical entanglement is suppressed by Kerr interaction due to photon blockage.We also find that the Kerr interaction can create the stationary entanglement and induce the resonance of entanglement in the small detuning regime.These results show that the Kerr interaction is an effective control for the optomechanical system. |
