Quantum synchronization of optomechanical systems — •Talitha Weiss1, Andreas Kronwald1, and Florian Marquardt1,21Institut für Theoretische Physik II, Friedrich-Alexander Universität Erlangen-Nürnberg, Staudtstraße 7, 91058 Erlangen — 2Max Planck Institute for the Science of Light, Günther-Scharowsky-Straße 1/Bau 24, 91058 Erlangen

Optomechanical arrays have been suggested as a novel system for studying many-body physics of interacting photons and phonons, and are experimentally realizable e.g. in optomechanical crystal structures. Driving all optomechanical systems into self-sustained oscillations can lead to synchronization.

We investigate how this synchronization is modified in the quantum regime by numerically simulating the full quantum behavior of two coupled optomechanical systems. In addition to the classically known synchronization regimes, we find parameter regions where quantum fluctuations drive transitions between different synchronization phases. We investigate the quantum to classical transition and how ideal synchronization is altered in presence of quantum fluctuations.
