本文研究了与双模SU(2)相干场相互作用的A型三能级原子系统中光场位相的动态特性,证明了光场每个模的位相及两个模的位相和均保持随机分布,给出了光场两个模位相差的平均值及方差表达式,探讨了系统初态及原子-光场耦合强度对光场两个模位相差涨落的影响,并揭示了在适当的条件下,系统呈现原子的相干捕获现象.

In this paper, the phase properties of two-mode SU(2) coherent field interacting with A-type three-level atom are investigated. We find that single-mode phase and the sum of the two-mode phase are all randomly distributed. The expressions of average value and variance of the phase difference are presented. The effects of atomic initial state and the atom-field coupling strengths on the variance of the phase difference are examined. That the atomic coherent trapping wil...
