  • We study the entanglement dynamics of the system composed of two two-level atoms resonantly interacting with two coupled cavities. The evolutions of atom-atom entanglement, cavity-cavity entanglement and atom-cavity entanglement are investigated. The influence of coupling constant between cavities on entanglement property is discussed. The numerical results show that atom-atom entanglement property is strengthened while atom-cavity entanglement property and cavity-cavity entanglement property are weakened with the increasing of the coupling constant between cavities.
