我们探讨了在特定系统对称性下，N耦合原子到一般玻色子库的动力学。在政权的多个原子耦合到一个单一的水库具有相同的耦合，我们确定显着的效果，值得注意的是，原子激发态振幅的初始配置强烈影响系统的动力学，甚至可以完全切断系统从它的环境。此外，我们发现，激发态的稳态振幅变得独立的水库的选择。引入的框架被应用到一个结构化的光子水库与光子晶体，在那里我们表明它再现以前的理论和实验结果，它预测超辐射行为内的单激发制度。
We explore the dynamics of N coupled atoms to a generic bosonic reservoir under specific system symmetries. In the regime of multiple atoms coupled to a single reservoir with identical couplings, we identify remarkable effects, notably that the initial configuration of the atomic excited state amplitudes strongly impacts the dynamics of the system and can even fully sever the system from its environment. Additionally, we find that steady state amplitudes of the excited states become independent of the choice of the reservoir. The framework introduced is applied to a structured photonic reservoir associated with a photonic crystal, where we show it reproduces previous theoretical and experimental results and it predicts superradiant behaviour within the single-excitation regime.
