Abstract: | In this paper, the entanglement of two moving atoms
induced by a single-mode field via a three-photon process is
investigated. It is shown that the entanglement is dependent on the
category of the field, the average photon number N, the number p
of half-wave lengths of the field mode and the atomic initial state.
Also, the sudden death and the sudden birth of the entanglement are
detected in this model and the results show that the existence of the
sudden death and the sudden birth depends on the parameter and the
category of the mode field. In addition, the three-photon process is a higher
order nonlinear process. |
