Nanofiber-mediated radiative transfer between two distant atoms

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.
