Optomechanical limit cycles in the quantum regime — •Niels Lörch and Klemens Hammerer — Institut für Theoretische Physik, Leibniz Universität Hannover and Max-Planck-Institut für Gravitationsphysik (Albert-Einstein-Institut), Callinstr. 38, 30167 Hannover, Germany

Optomechanical systems can exhibit self-sustained oscillations where the quantum state of the mechanical resonator possesses nonclassical characteristics such as sub-Poissonian phonon statistics and negative Wigner function density. Using laser theory we derive conditions on the system parameters to prepare such nonclassical states for different experimental setups in steady state.
