| 摘 要： | 利用全量子理论，讨论了克尔媒质中耦合V型三能级原子与相干态光场相互作用过程中原子信息熵的演化特性。数值计算结果表明，原子信息熵的演化特性对系统初始时刻场平均光子数的大小很敏感。初始时刻场的平均光子数比较大时，原子信息熵的演化会出现明显的周期性崩塌和回复现象。初态中原子激发态概率幅、原子间耦合强度、失谐量与克尔系数等系统...

| Abstract: | The information entropy properties of the coupled V-type three-level atoms interacting with the coherent field are studied by means of quantum theory.Numerical calculation results show that the average photon number in the initial state plays an important role in the time evolutions of the atomic information entropy.When the average photon number in the initial state is large,the time evolution of the atomic information entropy exhibits apparent collapse and revival phenomenon.The amplitude of the excited s... |
