Kerr介质中k光子J-C模型原子信息熵的演化特性

Evolution characteristic of atomic information entropy in k-photon J-C modei with Kerr medium

本文讨论了考虑Kerr介质的非线性耦合作用时k光子J-C模型中原子信息熵的演化性质。通过计算得到了原子信息熵随时间的演化特性,分析表明Kerr效应越大,原子信息熵明显减小。多光子过程使原子的信息熵增大,而相干态光场的强度对其也有明显的影响。并且对这些影响的物理机制作了必要的解释。

In this paper considering the nonlinear coupling of Kerr Medium, we study the time evolution of atomic information entropy in k-photon J-C Model. We find that the Kerr effect will decrease the atomic information entropy. Multi-photon process will increase the atomic information entropy. The intensity of coherent field also exhibits the strong influence on the atomic information entropy. And the explanation for the mechanism of these influences is given.
