In this paper,the Tavis-Cummings model is generalized to simultaneously consider the atomic motion and the field via intensity dependent coupling.Under the conditions of vacuum field,weakly and strongly coherent field,the entanglement evolution properties of two-atom-field and two-atom-two-atom are investigated using atomic reduced entropy and concurrence,respectively.According to evolution characteristics above,we prepare the W-class states of two-atom-field,two-atom Bell state,fidelity state of Bell-state...
