Collectively enhanced chiral photon emission from an atomic array near a nanofiber (2020)
Journal Article

Emitter ensembles interact collectively with the radiation field. In the case of a one-dimensional array of atoms near a nanofiber, this collective light-matter interaction does not only lead to an increased photon coupling to the guided modes within...
