The study of the nonequilibrium dynamics of driven and damped nonlinear mechanical resonators has gained attention in the last decades thanks to rapid developments in the fields of electro- and optomechanical systems in the micro and nano scales. Such resonators are typically characterized by very high frequencies, extremely small masses, and weak damping. As such, they are naturally being developed for a variety of novel applications such as sensing with unprecedented accuracy, but are also being used for studying fundamental physics at small scales—exploring mesoscopic phenomena, studying nonlinear dynamics, and quite recently also approaching full quantum behaviour. The aim of this lecture is to provide an overview of some of the nonequilibrium dynamical phenomena observed in these systems, while highlighting the common concepts and theoretical tools that have been developed for dealing with them.
