摘要
研究了充满Kerr介质的高Q腔中非关联双模压缩相干态场与V型三能级原子相互作用系统原子能级布居概率及两模场量子统计特性的时间演化.发现能级布居概率曲线有一附加结构,压缩参数仅对崩坍-复原的主结构有影响,对附加结构没有影响.双模互关联函数的时间演化曲线随压缩参数的增大起伏变小;一模为压缩真空态时,互关联函数起伏加剧.光场二阶相干度的时间演化也随压缩参数的增大起伏变小;压缩真空态的二阶相干度随压缩参数的增大起伏变小.
Abstract
In this paper we have studied the interacting system of a V-type three-level atom with uncorrelated two-mode squeezed coherent states in a high-Q cavity filled with Kerr-like medium. It is shown by numerical calculation that the time evolution of atomic level occupation has a additional structure, the correlation function and the degree of second-order coherence of the uncorrelated two-mode squeezed light field are affected by squeezing parameters and Kerr medium. The fluctuation of the time evolution curve is decreased when the squeezing parameters are increased. In addition, the Kerr medium caused a low-frequency fluctuation on the time evolution curve.
