论文摘要
我们计算了一个和两个两级原子与光学纳米纤维附近的电磁真空场相互作用的动力学，而无需进行诞生或马尔可夫近似。我们使用恒定的介电函数和Drude-Lorentz模型，观察到与标准的超级和子速度衰减的偏差。尽管存在非平凡的环境相关性，但我们讨论了将原子 - 原子通信速度与引导场的组速度的速度近似的有效性。我们的工作对在波导QED的量子光学应用程序中使用量子器应用程序中常用近似值的有效性有了更深入的了解。
We calculate the dynamics of one and two two-level atoms interacting with the electromagnetic vacuum field in the vicinity of an optical nanofiber without making either the Born or the Markov approximations. We use a constant dielectric function and the Drude-Lorentz model, observing deviations from the standard super- and sub-radiant decays. Despite the non-trivial environment correlations, we discuss the validity of approximating the speed of atom-atom communication to the group velocity of the guided field. Our work presents a deeper understanding of the validity of commonly used approximations in recent platforms for quantum optics applications in the context of waveguide QED.
