| Abstract: | The entanglement dynamics between an isolated atom and a moving atominteracting with a cavity field is investigated. The results showthat there appears sudden death of entanglement between the isolatedatom and the moving atom and that the time of entanglement suddendeath (ESD) is independent of the initial state of the system. It isinteresting that the isolated atom can also entangle with a cavityfield, though they do not interact with each other originally, whichstems from the fact that the entanglement between the isolated atomand the moving atom may turn into the entanglement between theisolated atom and the cavity. |
