Query: Atom- photon entanglement beyond the multi-photon resonance condition   The density matrix equations of motion in near-degenerate three-level V-type
closed-loop atomic system are calculated numerically in Floquet frame. The
dynamical behavior of atom- photon entanglement between the dressed atom and
its spontaneous emission is studied in semi classical approach beyond the
two-photon resonance condition in such a system. The quantum entropy of these
two subsystems is investigated by using the von Neumann entropy. It is shown
that, the degree of entanglement measure (DEM) can be controlled via the
intensity and the detuning of coupling optical field and quantum interference
induced by spontaneous emission. Moreover in the absence of quantum
interference the steady state behavior of DEM can be achieved even in beyond
the two- photon resonance condition. Furthermore in the absence of quantum
interference for special parameters of Rabi frequency and detuning of driving
laser field disentanglement can be occurred. Also the electromagnetically
induced transparency condition can be obtained when the system is disentangled.
