Dynamics of hybrid optomechanical systems — •Timo Holz, Marc Bienert, and Ralf Betzholz — Universität des Saarlandes, Saarbrücken, Germany

We explore the quantum dynamics of a hybrid optomechanical system composed of a two-level atom and an optical cavity with a moveable end-mirror. The interaction between the atom and the cavity mode is described by the Jaynes-Cummings interaction. The standard Hamiltonian of optomechanics specifies the phonon-photon interaction. We investigate the coherent time evolution of quantum states of the composite system in different parameter regimes both numerically and analytically. We analyse how non-classical states can be prepared and seek for a description of effective interactions between the different components of the hybrid system. Moreover, we discuss the influence of decoherence on the time evolution.
