摘要

The dynamics of entanglement and quantum discord (QD) between two two-level atoms interacting with two dissipative coupled cavities in the presence of initial atom-cavity correlations is investigated.In comparison with the result of the initial factorized state,we show that the initial state contained quantum correlation of atom-cavity is most robust against the dissipative environment,and the initial atom-cavity correlations,especially the quantum correlation,play a constructive role in the generation of atomic entanglement and QD.Simultaneously,the comparison between Markovian and non-Markovian dynamics,and the influences of inter-cavity hopping rate are also taken into account and analyzed.
