论文摘要
我们研究了一种在原子集合中共享的单个激发的动力学，并耦合到一维波指南。物质和光场之间的耦合产生了集体现象，例如具有增强初始衰减速率的超级状态，也引起了原子之间激发的连贯交换。我们发现，这两种现象之间的竞争为激发的衰减提供了一种特征动力学，并且显着表现出代数行为，而不是预期的标准指数为大量原子。该分析首先是针对手性波导进行的，可以通过分析解决问题，然后扩展到双向波导。
We study the dynamics of a single excitation coherently shared amongst an ensemble of atoms and coupled to a one-dimensional wave guide. The coupling between the matter and the light field gives rise to collective phenomena such as superradiant states with an enhanced initial decay rate, but also to the coherent exchange of the excitation between the atoms. We find that the competition between the two phenomena provides a characteristic dynamics for the decay of the excitations, and remarkably exhibits an algebraic behavior, instead of the expected standard exponential one, for a large number of atoms. The analysis is first performed for a chiral waveguide, where the problem can be solved analytically, and then is extended to the bidirectional waveguide.
