Research Abstract
Temporal evolution is studied for total entropy, the entropy difference and the sum of negative eigenvalues of the partially transposed
density matrix as quantitative entanglement measurements for JC model in a phase-damped cavity in the dispersive approximation. The
cavity field is assumed to be coupled to a reservoir with a phase-damping coupling. The case of a statistical mixture (SM) of coherent
states is considered as initial field state. The effects of cavity phase damping on the entanglement between the field and the atom are
studied.
