Cooperative behavior of quantum dipole emitters coupled to a zero-index nanoscale waveguide

摘要: We study cooperative behavior of quantum dipole emitters coupled to a rectangular waveguide with dielectric core and silver cladding. investigate emission inter-emitter entanglement generation phenomena for whose resonant frequencies are near the frequency cutoff waveguide, where effectively behaves as zero-index metamaterial. show that coupling allows one relax constraint on precision positioning observing extend spatial scale at which superradiance can be observed.
