论文摘要
在本文中，我们报告了$^{87} \ text {rb} $ atom $^{87} \ text {rb} $ ATOM的数值计算的数值计算。我们研究了这些量如何取决于纤维的半径，原子到纤维的距离，原子角动量极化的方向以及不同的原子量子数。我们还研究了四极转变的贡献，这对于高度两极分化的Rydberg州可能是重要的。我们的计算是基于二元格林的功能方法在宏观量子电动力学形式主义中进行的。这使我们可以考虑二氧化硅的分散性和吸收性特征。这是至关重要的，因为Rydberg Atoms沿着许多不同的过渡发出，其频率涵盖了广泛的电磁光谱。我们的工作是构建Rydberg原子纳米纤维界面的重要第一步，以实现量子光学和量子信息目的。
In this paper, we report on numerical calculations of the spontaneous emission rates and Lamb shifts of a $^{87}\text{Rb}$ atom in a Rydberg-excited state $\left(n\leq30\right)$ located close to a silica optical nanofiber. We investigate how these quantities depend on the fiber's radius, the distance of the atom to the fiber, the direction of the atomic angular momentum polarization as well as the different atomic quantum numbers. We also study the contribution of quadrupolar transitions, which may be substantial for highly polarizable Rydberg states. Our calculations are performed in the macroscopic quantum electrodynamics formalism, based on the dyadic Green's function method. This allows us to take dispersive and absorptive characteristics of silica into account; this is of major importance since Rydberg atoms emit along many different transitions whose frequencies cover a wide range of the electromagnetic spectrum. Our work is an important initial step towards building a Rydberg atom-nanofiber interface for quantum optics and quantum information purposes.
