Crossover from a delocalized to localized atomic excitation in an atom–waveguide interface
Crossover from a delocalized to localized atomic excitation in an atom–waveguide interface
Abstract An atom–waveguide system, which presents one of the quantum interfaces that enable strong couplings between light and atoms, can support tightly-confined guided modes of light. In this distinctive quantum interface, we theoretically investigate the crossover from a delocalized to localized atomic excitation under long-range dipole–dipole interactions and lattice disorders. …
