论文摘要
我们概述了从量子纳米光子学的角度来看宏观量子电动力学的框架。特别是，我们将注意力集中在理论的三个方面上，这对于描述纳米光结构中量子光学现象至关重要。首先，我们回顾了轻度互动汉密尔顿本身，特别强调了其规格独立性以及最小和多极耦合方案。其次，我们讨论了通过经典电磁场对量子光系统进行外部泵送的处理。第三，我们在多Emitter配置中引入了一个精确，完整和最小的字段量化基础，该配置基于所谓的以发射极为中心的模式。最后，我们在特定的杂化金属纤维几何形状中说明了这种量化方法：将两个量子发射器放置在嵌入sin微型风格中的Ag纳米球二聚体附近。
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 which 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 multi-emitter 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.
