The coherent backscattering spectrum of two atoms — •Vyacheslav Shatokhin¹, Thomas Wellens², Benoit Gremaud³, and Andreas Buchleitner⁴ — ¹B.I. Stepanov Institute of Physics, National Academy of Sciences, Nazavisimosti Avenue 68, 220072 Minsk, Belarus — ²Institut für Theoretische Physik, Universität Erlangen-Nürnberg, Staudtstr. 7, 91058 Erlangen, Germany — ³Laboratoire Kastler Brossel, Université Pierre et Marie Curie, 4 Place Jussieu, 75252 Paris Cedex 05, France — ⁴Max-Planck-Institut für Physik komplexer Systeme, Nöthnitzer Str. 38, 01187 Dresden, Germany

We present a detailed analytical and numerical analysis of the inelastic coherent backscattering spectrum of laser light incident on cold atoms. We identify frequency domains where the interference contribution can be positive or negative, or exhibit dispersive features. These distinctive features are explained by reciprocity arguments and dressed state two-photon scattering amplitudes.
