Collective current rectification

We consider a set of coupled underdamped ac-driven dynamical units exposed to a heat bath. The coupling scheme defines the absence/presence of certain symmetries, which in turn cause a nonzero/zero value of a mean dc-output. We discuss dynamical mechanisms of a dc-current appearance and identify current reversals with synchronization/desynchronization transitions in the collective ratchet's dynamics.
