Abstract
We give the exact analytical description for the dynamics of an atom coupled to field mode in dissipative cavity by using the master equation. The effects of thermal photon (n≠0) on entanglement and coherence loss are achievement. It is found that the field is inhibited from going into a pure state and coherence is lost faster than in the case of zero temperature (n=0).
