Antibunching Effect of Field State in a System of a Moving Two-level Atom Interacting with Number-chaotic State Light via Multi-photon Transition

摘要/Abstract

摘要:

利用全量子理论,研究了多光子跃迁下数字混沌态(the number-chaotic state),NCS光场与运动二能级原子相互作用系统光场的反聚束效应.讨论了原子的初始状态、数态光子数、热平均光子数、跃迁光子数、场模结构参数对光场反聚束效应的影响.结果表明:原子的初始状态、热平均光子数影响光场反聚束效应的振幅大小;场模结构参数影响光场反聚束效应的振荡规律与振荡周期;数态光子数及跃迁光子数选取不同,光场反聚束效应的演化曲线表现出不同的规律.

Abstract:

The antibunching effect of the optical field in a system of a moving two-level atom interacting with the number-chaotic state(NCS) light via a multi-photon transition is studied by means of the full quantum theory.The influences of atomic initial state and the parameters,including field-mode structure parameter,the average photon number of the chaotic state and the photon number of the number state.on the antibunching of the optical field are analyzed.The results show that atomic initial state and average photon number of the chaotic state affect the amplitude of the antibunching effect.The field-mode structure parameter is correlated with the oscillation period and form of the antibunching effect.When the photon number of the number state and transitional photon number are at different values,the evolution curves of the antibunching effect have different manners.
