摘　　要：研究了一个二能级原子与相干光场多光子相互作用下场熵演化的动力学特性In this paper, the dynamical properties of the field entropy in the multiphoton Jaynes-Cummings model are studied. It is showed that the evolution of field entropy has no periodicity and is influenced by the initial states of atoms and the initial phase of the field.
