Description
Summary:Quantum entanglement dynamics for two atoms trapped in two coupled cavities is investigated, Numerical results show that the present of the two atomic excitations is mainly accounted for the entanglement-sudden-death （ESD） effect with the two cavities initially in the vacuum. The entanglement can also be controlled by the hopping rate and the imbalances between the two atom-cavity coupling rates.
