In this paper, we investigate the entanglement dynamics of a two-level atom with a single-mode quantized field in a damped cavity optomechanics system in the presence of a driving laser. To achieve this purpose, after obtaining the effective Hamiltonian we added a suitable dissipation term to it. Then, we evaluate the explicit time-dependent form of the state vector of the whole system by choosing particular initial conditions for atom, field and the oscillatory mirror and finally, we calculate the time evolution of linear entropy as a measure of entanglement. The results show that the dissipation reduces the amount of entanglement between the atom and the subsystem consisting of the field and mirror.
Keywords: linear entropy, entanglement, cavity optomechanics, effective Hamiltonian.
