【Abstract】 in this paper,the properties of the evolution of the field entropy in the vacuum-state multiphoton J-C model have been investigated.The influences of atomic coherence,of detuning parameter and of transition photon number on the field entropy have been discussed.The evolution of the field entropy in the vacuum-state multiphoton J-C model iscompared with those in the themal and the coherent light field J-C models.更多还原
