论文摘要
我们建立了一个通用框架，用于研究结合状态和量子发射器的光子发射动力学，并与结构化的纳米光晶格结合使用，并具有工程耗散（损失）。在单个兴奋行业中，可以通过非温和形式主义来描述系统。我们已经在随附的字母[gong \ emph {et al}。，arxiv：2205.05479]中指出，一个与一维的非弱点晶格耦合的单个发射极可能已经在没有遗产的情况下表现出异常行为。在这里，我们提供了有关这些观察结果的更多详细信息。我们还提供了有关具有多个量子发射器或更高维度的情况的其他几个示例。我们的作品揭示了耗散性纳米光学系统中丰富的非富米现象的冰山一角。
We establish a general framework for studying the bound states and the photon-emission dynamics of quantum emitters coupled to structured nanophotonic lattices with engineered dissipation (loss). In the single-excitation sector, the system can be described exactly by a non-Hermitian formalism. We have pointed out in the accompanying letter [Gong \emph{et al}., arXiv:2205.05479] that a single emitter coupled to a one-dimensional non-Hermitian lattice may already exhibit anomalous behaviors without Hermitian counterparts. Here we provide further detail on these observations. We also present several additional examples on the cases with multiple quantum emitters or in higher dimensions. Our work unveils the tip of the iceberg of the rich non-Hermitian phenomena in dissipative nanophotonic systems.
