Field Entropy Evolution of Entangled Atoms Interacting with Coherent State Light-field in T-CModel
摘要/Abstract
利用全量子理论,研究了一对纠缠原子与相干态光场相互作用中场熵的演化特性.讨论了原子间偶极-偶极相互作用、光场强度与2原子纠缠度对场熵演化特性的影响.结果表明:原子间偶极-偶极相互作用强度增加使场熵的演化周期增大;初始光场强度增加,场熵平均值先增大后减小,振荡周期变大;场熵平均值随初始纠缠度增大反而减小,但振荡幅度随初始纠缠度增大而增大.
The field entropy evolution of two entangled-atoms interacting with coherent state light-f iled is studied by means of quantum theory.The influence of the dipole-dipole interaction,the intensity of field and the two-atom's entanglement on the field entropy properties are studied.The results show that the increasing of the atomic dipole-dipole interaction will increase evolution period of field entropy.The mean-value of entropy will increase at first and then decrease with the intensity of field increasing.The oscillation period of field entropy increases with the increase of the intensity of field.The mean-value of field entropy will decrease with the increasing of atoms' entang lement,but the oscillation of fieldent ropy will increase with the increasing of the entanglement of atoms .
