AI 中文摘要
我们探究当充分考虑量子发射体的多能级性质时光与物质的集体态如何不同。对于间距紧密的发射体，近共振跃迁间的干涉与二能级近似相比完全改变了集体态的特性。特别地，我们发现了超辐射发生时发射体间距的下限，而二能级发射体不存在此下限。相反，对于发射体间距较大时，集体态类似于在广泛使用的发射体二能级近似中得到的那些。两种情况都可由捕获在光学晶格中的分子实现。因此我们提出分子候选并描述新出现的多能级干涉的实验特征。
英文摘要
We explore how collective states of light and matter differ when the multi-level nature of the quantum emitters is fully taken into account. For closely spaced emitters, interferences between near-resonant transitions completely change the character of the collective states compared to two-level approximations. In particular, we find a lower bound on the emitter separation for superradiance to occur which does not exist for two-level emitters. By contrast, for larger separations between the emitters, the collective states resemble those obtained within the widely used two-level approximation of the emitters. Both regimes may be realized by molecules trapped in optical lattices. We therefore propose molecular candidates and describe experimental signatures of emerging multi-level interference.
