Light-induced oscillations of a cavity mirror — •Max Ludwig, Clemens Neuenhahn, and Florian Marquardt — Sektion Physik, Arnold Sommerfeld Center for Theoretical Physics, and Center for NanoScience, Ludwig-Maximilians-Universität München, Theresienstr. 37, 80333 München

A Fabry-Perot cavity with a moving mirror represents one of the simplest examples where the radiation pressure interacts with micromechanical degrees of freedom. This can give rise to an instability leading to self-induced oscillations, as demonstrated in two recent experiments [1,2]. Our theory [3] predicted and explained multiple stable dynamical attractors of the resulting mechanical motion. Here, we extend this work to cover situations involving several light modes inside the cavity, as well as the chaotical regime of motion, displaying a rich variety of behaviour.

We present both analytical and numerical results and comment on the direct relevance for experiments [1,2].
