论文摘要
输入输出形式主义是研究光腔对外部刺激的响应的基础。现有理论通常仅使用一种内部模式处理腔系统。但是，人们对更复杂的系统的兴趣越来越大，尤其是混合腔体系统，该系统至少包含两个内部模式，分别来自光腔和物质。在这里，我们提出了一个图形循环理论，以计算和可视化这种多模式腔的反射和传输光谱，类似于Feynman图在量子场理论中的作用。该循环理论给出了统一的图片来解释在混合磁铁系统上的实验观测，并且在没有任何计算的情况下非常容易应用于任意复杂问题。
The input-output formalism is the basis to study the response of an optical cavity to the external stimulations. The existing theories usually handle cavity systems with only one internal mode. However, there is growing interest in more complex systems, especially the hybrid cavity-matter systems, which contains at least two internal modes, one or more from the optical cavity and the matter, respectively. Here we propose a graphical loop theory to calculate and visualize the reflection and transmission spectrum of such multi-mode cavity, resembling the role of Feynman diagrams in the quantum field theory. This loop theory gives a unified picture to interpret the experimental observations on a hybrid magnet-light system, and is extremely easy to apply to arbitrary complicated problems without any calculations.
