标题： Microcavities coupled to multilevel atoms

摘要： 一个三能级原子在$\Lambda$配置下与微腔耦合被研究。 原子的两个跃迁被假定耦合到腔内不同的反向传播模式对。 我们分析了在强耦合和腔质量较差极限下的动力学行为。 我们发现，与两能级装置相比，第三个原子态和额外的控制场模式显著改变了系统动力学，并实现了更先进的控制方案。 所有结果都通过适当的极化子态和本征模式表示进行解释。 作为潜在应用，我们讨论了光学开关和单电子传输操作以及探测靠近谐振器表面的粒子。 显示英文摘要

摘要： A three-level atom in the $\Lambda$-configuration coupled to a microcavity is studied. The two transitions of the atom are assumed couple to different counterpropagating mode pairs in the cavity. We analyze the dynamics both, in the strong-coupling and the bad cavity limit. We find that compared to a two-level setup, the third atomic state and the additional control field modes crucially modify the system dynamics and enable more advanced control schemes. All results are explained using appropriate dressed state and eigenmode representations. As potential applications, we discuss optical switching and turnstile operations and detection of particles close to the resonator surface.
