论文摘要
光子玻色$ - $ EINSTEIN冷凝物是最近观察到的耦合光晶体系统的集体基态。我们根据分散和吸收环境中的宏观量子电动力学来描述这种量子状态。为了建模耦合的光子$ - $染料动力学，我们使用嵌套的开放量子系统方法得出主方程，从而得出描述冷凝过程必不可少的所有参数。这种方法使我们能够描述任意形状的光子冷凝物，因为所有依赖几何衰减常数都可以用绿色的张量表示。特别是，我们获得了染料分子的空腔模式的吸收和排放速率。
The photonic Bose$-$Einstein condensate is a recently observed collective ground state of a coupled light-matter system. We describe this quantum state based on macroscopic quantum electrodynamics in dispersing and absorbing environments. To model the coupled photon$-$dye dynamics, we derive a master equation using a nested open quantum systems approach yielding all parameters essential to describe the condensation process. This approach allows us to describe photon condensates of arbitrary shapes because all geometry-dependent decay constants can be expressed in terms of the Green's tensor. In particular, we obtain the cavity mode absorption and emission rates of the dye molecules.
