Superradiance in 1D chains of multilvel atoms — •Aleksei V. Konovalov, Tom Schmit, and Giovanna Morigi — Universität des Saarlandes, Saarbrücken, Germany
We analyse the properties of the light coherently scattered by a periodic array of atoms when the distance between neighbouring atoms is comparable with the wavelength. We specifically focus on superradiant scattering and analyse it as a function of the array periodicity. We also account for the multilevel atomic structure, where several dipole transitions of the same atom couple to the incident light and can mutually interfere. Starting from the full quantum master equation [1], we determine the properties of the light by means of the coherent-dipole approximation [2]. We then determine the collective Lamb-shift for chains of Na23 and Rb87 atoms in experimentally relevant geometries.
