Abstract We present an overview of the framework of macroscopic quantum electrodynamics from a quantum nanophotonics perspective. Particularly, we focus our attention on three aspects of the theory that are crucial for the description of quantum optical phenomena in nanophotonic structures. First, we review the light–matter interaction Hamiltonian itself, with special emphasis on its gauge independence and the minimal and multipolar coupling schemes. Second, we discuss the treatment of the external pumping of quantum optical systems by classical electromagnetic fields. Third, we introduce an exact, complete, and minimal basis for the field quantization in multiemitter configurations, which is based on the so-called emitter-centered modes. Finally, we illustrate this quantization approach in a particular hybrid metallodielectric geometry: two quantum emitters placed in the vicinity of a dimer of Ag nanospheres embedded in a SiN microdisk.

用于量子纳米光子学的宏观 QED：以发射器为中心的模式作为多发射器问题的最小基础

摘要 我们从量子纳米光子学的角度概述了宏观量子电动力学的框架。特别是，我们将注意力集中在对描述纳米光子结构中的量子光学现象至关重要的理论的三个方面。首先，我们回顾光-物质相互作用哈密顿量本身，特别强调其规范独立性以及最小和多极耦合方案。其次，我们讨论了经典电磁场对量子光学系统外部泵浦的处理。第三，我们为多发射器配置中的场量化引入了一个精确、完整和最小的基础，它基于所谓的以发射器为中心的模式。最后，我们在特定的混合金属电介质几何结构中说明了这种量化方法：
