反Jaynes-Cummings模型下纠缠相干光场量子特性的研究

一个二能级原子在经典场的驱动下与单模光场相互作用，在强经典驱动和大失谐的情况下，原子与光场的相互作用可以化为有效的反Jaynes-Cummings模型.在该模型下主要研究了双模纠缠相干光场中的一束与受强经典场驱动的二能级原子相互作用，在演化过程中，对原子作选择性测量，即通过操纵参加相互作用光场的作用时间以及选择适当的光场参数，可以在较长的时间范围和较大的相干参数范围内很好地控制未参加相互作用的相干光场的量子统计特性，得到预期的非经典光场. 关键词： 量子光学 反Jaynes-Cummings模型 反聚束效应 压缩效应

Quantum properties of the entangled coherent light field under the anti-Jaynes-Cummings model

A two-level atom drvien by a strong classical field interacts with a single-mode light field, and the interaction between the atom and the light field can turn into an effective anti-Jaynes-Cummings model under the conditions of strong driving and large detuning. In this paper, we mainly study the two-mode entangled coherent light field in this model, in which one mode of the entangled coherent light field interacts with a two-level atom driven by a strong classical field. During the evolution of the total system, we make a selective measurement on the atom. Through tuning the evolution time and the parameter of the coherent field, we can easily control the quantum statistical properties of the other mode of the entangled light fields and generate the expected non-classical light field in a longer interaction time and a wider region of coherent parameter.
