Abstract
We investigate the entanglement dynamics and coherence loss of a two-level atom dispersively interacting with two coherent fields in a dissipative cavity by using the concurrence and linear entropy, respectively. It is shown that the atomic coherence can lead to entanglement between the atom and one mode while the two modes are always separable. We also find that there is long-lived coherence loss as the system evolves.
