二维原子阵列表现出许多有趣的量子光学现象，包括亚辐射、近乎完美的辐射反射和长寿命的拓扑边态。研究此类晶格中光子的发射和散射需要完整地处理单个原子的辐射模式，包括远程相互作用。我们描述了一个系统的方法来执行集体的能量转移和衰变率的计算中存在的这种长程相互作用的任意二维原子晶格。作为该方法的应用，我们研究了自由空间和近等离子体表面原子晶格的拓扑性质。
Two-dimensional atomic arrays exhibit a number of intriguing quantum optical phenomena, including subradiance, nearly perfect reflection of radiation, and long-lived topological edge states. Studies of emission and scattering of photons in such lattices require complete treatment of the radiation pattern from individual atoms, including long-range interactions. We describe a systematic approach to perform the calculations of collective energy shifts and decay rates in the presence of such long-range interactions for arbitrary two-dimensional atomic lattices. As applications of our method, we investigate the topological properties of atomic lattices both in free space and near plasmonic surfaces.
