Light scattering of an optomechanical cavity coupled to a single atom — Daniel Breyer and •Marc Bienert — Theoretische Physik, Universität des Saarlandes, Saarbrücken

We theoretically analyze the light scattering of an optomechanical cavity which strongly interacts with a single two-level system and couples simultaneously to a mechanical oscillator by radiation forces. The analysis is based on the assumptions that the system is driven at low intensity, and that the mechanical interaction is sufficiently weak, permitting a perturbative treatment. We find quantum interference in the scattering paths, which allows one to suppress the Stokes component of the scattered light. This effect can be exploited to reduce the motional energy of the mechanical oscillator.
