摘要
利用全量子化理论 ,研究了 Kerr介质中耦合二能级双原子与单模光场相互作用的场熵演化规律。结果表明 :Kerr介质和原子间的相互作用都影响着场熵演化的周期性 ,并使光场与原子的关联程度减弱 ;初始场强 n同样影响着场熵演化的周期性 ,且随着初始场强 n的增加 ,光场与原子的关联程度先增强后减弱。
In this paper,the field entropy evolution of two coupling atoms interacting with a single mode light field in Kerr medium is studied by means of the quantum theory.It has been shown that:the Kerr medium and the interaction of atoms will influence the periodicity of the evolution of the field entropy,make the connected degree between field and atoms weaken;the excited field intensity also influence the periodicity of the evolution of the field entropy,the connected degree between field and atoms is strengthened first and is weakened later when increases.
