Exact solution of entanglement of the double Jaynes–Cummings model without rotating wave approximation

doi:10.1088/1674-1056/19/9/090309

Abstract 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.

Keywords: concurrence sudden death atom–field coupling dipole–dipole interaction
