摘要
This paper investigates the influences of atom field coupling and dipole-dipole coupling for atoms on the entanglement between two atoms by means of concurrence, The results show that the sudden death occurs when the atom field coupling is strong enough, and the collapse and the revival appear when the dipole-dipole interaction is strong enough.
