通过实验与Floquet理论结合，利用Shirley方法分析缀饰态，揭示里德伯EIT光谱中避免交叉的物理机制，提供解释复杂光谱的强有力框架。
AI 中文摘要
我们提出了对里德伯原子交流斯塔克位移电磁感应透明（EIT）光谱中避免交叉的实验与Floquet理论联合研究。观察到的避免交叉结构无法仅由传统交流斯塔克图完全解释，后者提供能量位移但不揭示潜在的态组成和耦合路径。利用Shirley方法，我们分析Floquet本征态，以建立测量光谱与潜在缀饰态动力学之间的直接联系。通过追踪态混合、裸态组成和主导高阶Floquet耦合路径的演化，我们揭示了在不同主量子数和射频频率下形成避免交叉的物理机制。我们的结果表明，Floquet本征态分析为解释复杂的交流斯塔克位移里德伯-EIT光谱及其潜在的高阶Floquet耦合相互作用提供了强有力的框架。
英文摘要
We present a combined experimental and Floquet-theoretical study of avoided crossings in the AC Stark-shifted electromagnetically induced transparency (EIT) spectra of Rydberg atoms. Observed avoided-crossing structures cannot be fully explained by conventional AC Stark maps alone, which provide the energy shifts but do not reveal the underlying state composition and coupling pathways. Using the Shirley method, we analyze the Floquet eigenstates to establish a direct connection between the measured spectra and the underlying dressed-state dynamics. By tracking the evolution of state mixing, bare-state composition, and dominant higher-order Floquet coupling pathways, we reveal the physical mechanisms responsible for the formation of avoided crossings across different principal quantum numbers and RF frequencies. Our results demonstrate that Floquet-eigenstate analysis provides a powerful framework for interpreting complex AC Stark-shifted Rydberg-EIT spectra and the underlying higher-order Floquet coupling interactions.
