Stabilization of an optomechanical system via Pyragas control — •Nicolas L. Naumann, Julia Kabuss, and Andreas Knorr — Institut für Theoretische Physik, Nichtlineare Optik und Quantenelektronik, Technische Universität Berlin, Berlin, Germany

With a variety of possible applications (sensing devices, quantum information processing) and potentially revealing insights into the nature of quantum mechanics, optomechanical systems are currently subject to intense research. Our studies focus on the control of an optically pumped system, consisting of a cavity with one movable mirror. The moving mirror constitutes a source to nonlinearities, induced by radiation pressure [1]. To control the dynamics of this nonlinear system, we apply the widely used Pyragas control scheme [2] in oder to stabilize formerly unstable solutions.
