Signatures of nonclassicality in the non-linear dynamics of an optomechanical system — •Jiang Qian and Florian Marquardt — Arnold Sommerfeld Center for Theoretical Physics, LMU, Munich, Germany

We study the non-linear dynamics in the quantum mechanical time-evolution of an optomechanical system. We discuss the time-evolution of the mechanical Wigner density and discuss the parameter dependence of nonclassical signatures. We describe a long-term steady state that significantly deviates from the semiclassical coherent state picture.
