We introduce an analytical description of an open bimodal cavity containing a $\Lambda$-type three-level atom. We explore the effect of the atom–cavity nonlinear interaction, the cavity dissipation, and the initial coherent intensity on the dynamics of the nonclassical correlations for a cavity prepared initially in a superposition of nonlinear coherent states. The nonlinear interaction generates a regular entanglement between the subsystems, and populates the energy atomic states. We show that the collapse phenomenon is a good indicator of the generated quantum coherence. The growth of the entropy is used to explore the generated entanglement (if the dissipation is absent) and mixedness (in the presence of the dissipation). It is found that the generation and the robustness of the quantum synchronization and the correlations between the subsystems are very sensitive to the dissipation, the superposition, and the coherent intensity of the initial Barut–Girardello coherent states.

SU（3）系统与两个开放参数放大器模式相互作用的非经典特性的动力学

我们介绍一个包含$ \ Lambda $的开放双峰腔的分析描述。型三能级原子。我们探讨了原子-腔非线性相互作用，腔耗散和初始相干强度对最初以非线性相干态叠加制备的腔的非经典相关动力学的影响。非线性相互作用在子系统之间产生规则的纠缠，并填充能量原子态。我们表明，崩溃现象是产生的量子相干性的良好指示。熵的增长用于探究产生的纠缠（如果不存在耗散）和混合（在存在耗散的情况下）。发现量子同步的产生和鲁棒性以及子系统之间的相关性对耗散，叠加，
