Correlation and entanglement of a three-level atom inside a dissipative cavity

► Dynamical properties of quantum and classical entropy of moving three-level atom in the presence of damping. ► Initial state setting of the atom and the quantized field. ► Effects of the atomic motion and phase damping. ► Generation of the long lived entanglement and short disentanglement. ► Strong connection between atomic Wehrl entropy through marginal atomic Q function and entanglement.
