| Abstract: | We investigate the system of Bose-Einstein condensates interacting with SU(1, 1) coherent state in two-photon transition process, the entanglement of atom-field and the entanglement between the two-mode light field using the quantum reduced entropy and quantum relative entropy are studied,respectively. The influences of the coherent parameter of light field, two-mode photon number difference and interaction between atoms on the evolution of the entanglement of atom-field and the entanglement between the two-mode light field have been discussed. |
