我们研究了纳米纤维附近一对二能级原子的自发发射。我们证明了由纳米纤维的引导模式介导的远距离原子之间的大量辐射交换。这种交换分别导致子辐射态和超辐射态寿命的增加和减少。我们的分析是基于海森堡-朗格万理论和主方程形式主义框架下光纤的辐射模和导模的完全量子化。
We study spontaneous emission from a pair of two-level atoms near a nanofiber. We demonstrate a substantial radiative exchange between distant atoms mediated by the guided modes of the nanofiber. The exchange is shown to lead to increased and decreased lifetimes of the subradiant and superradiant states, respectively. Our analysis is based on the full quantization of both the radiation and guided modes of the fiber in the framework of the Heisenberg-Langevin theory and the master equation formalism.
