Photon scattering by an atomic ensemble coupled to a one-dimensional nanophotonic waveguide
We theoretically investigate the quantum scattering of a weak coherent input field interacting with an ensemble of $\mathrm{\ensuremath{\Lambda}}$-type three-level atoms coupled to a one-dimensional waveguide. With an effective non-Hermitian Hamiltonian, we study the collective interaction between the atoms mediated by the waveguide mode. In our scheme, the atoms are randomly …
