Quantum Dynamics of Nanomechanical Resonator Arrays — •Max Ludwig and Florian Marquardt — Arnold-Sommerfeld Center for Theoretical Physics, Center for NanoScience and Department of Physics, Ludwig-Maximilians Universiät München, Munich, Germany

We investigate the nonequilibrium quantum dynamics of arrays of coupled nanoresonators, where the coupling constants can be tuned in a time-dependent manner. In our numerical simulations, we take into account dissipation effects via a Lindblad master equation approach, and discuss the influence of different initial state preparations. We visualize the dynamics in terms of the Wigner density evolution of the individual resonators.
