摘要/Abstract

摘要： 基于非简并双光子Jaynes-Cummings 模型研究了对相干态光场的各种非经典性质，例如光场的反群聚效应，Cauchy-Schwarz不等式违背，光场的双模压缩性质等.结果表明，通过选择一定的参量或者通过选择性地探测原子内态，能使上述非经典性质得到明显增强.此外，使用型三能级原子与对相干态光场作用和使用型三能级原子与光场作用相比，各种非经典性质（包括反群聚效应、Cauchy-Schwarz 不等式违背）可以获得更佳的效果.

Abstract: The nonclassical properties (such as antibunching effect, violation of Cauchy-Schwarz inequality and two-mode squeezing) of the pair coherent states based on a non-degenerate two-photon Jaynes-Cummings model were investigated. It is shown that these nonclassical properties can be enhanced in the case that the coefficients are chosen appropriately or that the atom is selectively detected. In addition, it seems that all kinds of the nonclassical properties (including antibunching effect and violation of Cauchy-Schwarz inequality)by using -type three-level atom are more effective than that using -type three-level atom.

Key words: quantum optics, nonclassical properties, non-degenerate two-photon Jaynes-Cummings model, pair coherent states
