Influence of the Phase on the Entanglement between a Jaynes-Cummings Atom and an Isolated Atom

A scheme is presented to generate an entangled atomic state, for which the quantum phase aects the atom atom entanglement when the atom interacts with external light elds. The quantum phase enhances the entanglement and extends the time that the system stays in stronger entanglement state or the phase makes the system more robust. It is also shown that the quantum phase is able to delay the entanglement sudden death and hasten the entanglement revival.
