摘要

我们通过实验研究了在两种相互竞争的相互作用下光学驱动的原子多级系统的级混合、分裂和排斥。光学耦合的强度不断增加,直到超过负责混合磁性子态的原子超频相互作用。由于耦合态空间的多电平特性,电平移动表现出复杂的行为,让人联想到帕申-贝克效应。我们的研究结果表明,多级效应会对强外部驱动产生重大影响,这与有效非相互作用两级系统的简单模型不同。这些结果凸显了强光驱动系统中光偏振或初始状态准备不完善的相关性。

Competing interactions in strongly driven multi-level systems
We experimentally study the level mixing, splitting and repulsion of an optically driven atomic multi-level system under two competing interactions. The strength of the optical coupling is increased until it surpasses the atomic hyperfine interaction responsible for mixing the magnetic substates. Due to the multi-level character of the coupled state space, the level shifts exhibit complex behavior reminiscent of the Paschen–Back effect. Our results show that multi-level effects can have significant influence for strong external drive, differing from a simple model of effective non-interacting two-level systems. These results highlight the relevance of imperfections of the light polarization or initial state preparation in strongly optically driven systems.
