我们开发了一种有效场论（EFT）来描述一维里德伯极化子的少体和多体传播。我们表明，通过将传播问题映射到非平衡淬灭（其中时间和空间的作用相反），可以发现通过里德伯介质的光子传输。我们在 EFT 中加入了有效范围校正，并表明它们在存在深束缚态的情况下主导着散射共振附近的动力学。最后，我们展示了里德伯-里德伯相互作用的长程性质如何诱导里德伯极化激元之间强有效的 N 体相互作用。这些结果为使用里德伯极化激元研究量子场论中的非微扰效应铺平了道路。
We develop an effective field theory (EFT) to describe the few- and many-body propagation of one dimensional Rydberg polaritons. We show that the photonic transmission through the Rydberg medium can be found by mapping the propagation problem to a non-equilibrium quench, where the role of time and space are reversed. We include effective range corrections in the EFT and show that they dominate the dynamics near scattering resonances in the presence of deep bound states. Finally, we show how the long-range nature of the Rydberg-Rydberg interactions induces strong effective N-body interactions between Rydberg polaritons. These results pave the way towards studying non-perturbative effects in quantum field theories using Rydberg polaritons.
