  An experimentally realizable model based on the interaction between an
excited two-level atom and a radiation field inside two quantum electrodynamics
cavities is proposed. It consists of sending an excited two-level atom through
two serial cavities which contain the radiation field. Hence, the Lindblad
master equation described the reduced density matrix of the joint-joint field
system inside the cavities is exactly solved in Markovian and non-Markovian
regimes. However, the rate of entanglement inherent in the total field-field
system are evaluated using various witnesses of entanglement such as
concurrence, logarithmic negativity and quantum discord. Moreover, the
non-classicality by means of negativity volume and Wigner function is
discussed. Finally, two schemes of quantum teleportation are suggested.
