The optomechanical damping basis — •Juan Mauricio Torres1, Ralf Betzholz2, and Marc Bienert21Institut für Angewandte Physik, Technische Universität Darmstadt, D-64289 Germany — 2Theoretische Physik, Universität des Saarlandes, D-66123 Saarbrücken, Germany

We present the solution to the eigenvalue problem of the Lindblad master equation describing an optomechanical setup. The set of eigenvectors of the corresponding Liouville operator is called the damping basis [1]. The system consists of an optical mode representing the electromagnetic field inside a cavity with a moving mirror which stands for the mechanical mode. The effects of loses are taken into account by assuming a contact to two separate baths of zero and non-zero temperature for the optical and mechanical mode respectively. As an application, we present analytical calculations of the output spectrum of the cavity and time dependent correlation functions of the system operators.
