THE ATOMIC AND THE FIELD DISENTANGLED STATES AND ITS EVOLUTION PROPERTY IN THE INTENSITY DEPENDENT COUPLING JAYNES CUMMINGS MODEL 

分析了依赖强度耦合ＪａｙｎｅｓＣｕｍｍｉｎｇｓ模型在初始相干光场较强的情况下（ｎ１）原子和场退耦合的条件，详细地研究了对于不同的原子初态原子和场的各种ｄｉｓｅｎｔａｎｇｌｅｄｓｔａｔｅｓ的确切表达式及其演化的周期性，并且用密度算符间的距离对原子和场的这些ｄｉｓｅｎｔａｎｇｌｅｄｓｔａｔｅｓ及其演化进行了充分的论证．

Abstract In this paper, the disentanglement conditions in the intensity dependent coupling Jaynes Cummings model are derived for large initial field ( 1). The atomic and the field disentangled states are investigated in detail for varied initial atomic state, these disentangled states and the periodicity of the dynamical evolution are examined by the distance between density operators.
