ABĀ - In the present report, temporal behavior of entanglement between a photonic binomial distribution and a two-level atom in a leaky cavity, in equilibrium with the environment at a temperature T, is studied. In this regard, the master equation is solved in the secular approximation for the density matrix, when the initial photonic distribution is binomial. The atom-photon density matrix so calculated is then used to compute the negativity, as a measure of entanglement. The behavior of entanglement is, consequently, determined as functions of time and temperature. Our results, along with representative figures reveal that the atom-photon degree of entanglement exhibits oscillations while decaying with time and asymptotically vanishes. It is further demonstrated that an increase in the temperature results a decrease in the entanglement.
