摘要

在两类非线性类克尔介质（NKLM）中评估了包含五级原子（5LA）和两个量子系统（2QS）的光学模型的统计测量结果。两个量子系统分别代表波色子系统和苏(1,1)系统。建议5LA和2QS的构型为（\mathfrak {X}\）型。5LA 初始状态处于激发态，波色子和 SU(1,1) 量子系统分别处于相干态和巴鲁特-吉拉尔德罗态。非线性类克尔介质代表了两个量子系统的两种不同类型。对著名的统计量进行了评估和分析，如种群反转、香农熵、自相关性、相干性和考希-施瓦茨不等式。讨论了克尔参数在拟议统计测量中的有效性。

Effectiveness of Nonlinear Kerr Medium in Statistical Measurements of \(\mathfrak {X}\)-type Five-Level Atom and Two Quantum Systems

Statistical measurements for an optics model containing a five-level atom (5LA) and two quantum systems (2QS) are evaluated into two types of nonlinear Kerr-like media (NKLM). Two quantum systems represent the Boson and SU(1,1) systems. Suggest that the configuration of the 5LA and 2QS is \(\mathfrak {X}\)-type. The 5LA initial state is in excited state as well as the Boson and SU(1,1) quantum systems are in coherent and Barut-Girardello states, respectively. The nonlinear Kerr-like medium represents two different types for two quantum systems. Well-famous statistical measures such as population inversion, Shannon entropy, autocorrelation, coherence, and Cauchy-Schwarz inequality are evaluated and analyzed. The effectiveness of Kerr parameters in the proposed statistical measurements are discussed.
