标题： Spatially resolved photon statistics of general nanophotonic systems

摘要： 尽管光子关联的实验测量在实验室中已成为常规，但对于复杂纳米光子器件产生的光，理论上的获取仍然是一个主要挑战。 当前的方法仅限于特定的简化情况，缺乏普遍性。 在此，我们提出一种新方法，可在任意电磁环境中实现空间和频率分辨的光子统计。 在宏观量子电动力学框架内，我们开发了一种实用工具，通过包括作为场探测器的损耗双能级系统，来计算复杂量子系统的电场关联。 为了使实现可行，我们使用了一种最近开发的多发射器少模量化方法，以正确考虑光子向探测器的完全延迟传播。 我们通过研究靠近等离子体纳米粒子的一个和两个发射器的光子关联，证明了所提出技术的有效性和鲁棒性。 模拟结果显示，即使在这些相对简单的配置中，光统计也表现出强烈的角依赖性。 这些结果强调了超越传统量子光学方法的重要性，以充分捕捉分析的物理效应，并实现对实际纳米光子器件中量子光生成的研究。 显示英文摘要

摘要： While experimental measurements of photon correlations have become routine in laboratories, theoretical access to these quantities for the light generated in complex nanophotonic devices remains a major challenge. Current methods are limited to specific simplified cases and lack generality. Here we present a novel method that provides access to photon statistics resolved in space and frequency in arbitrary electromagnetic environments. Within the macroscopic QED framework, we develop a practical tool to compute electric field correlations for complex quantum systems by including lossy two-level systems that act as field detectors within the system. To make the implementation feasible, we use a recently developed multi-emitter few-mode quantization method to correctly account for fully retarded light propagation to the detectors. We demonstrate the effectiveness and robustness of the proposed technique by studying the photon correlations of one and two emitters in close proximity to a plasmonic nanoparticle. The simulations show that even in these relatively simple configurations, the light statistics exhibit a strong angular dependence. These results highlight the importance of going beyond conventional quantum-optical approaches to fully capture the analyzed physical effects and enable the study of the quantum light generation in realistic nanophotonic devices.
