Supercritical Kuramoto oscillators with distributed frequencies can be separated into two disjoint groups: an ordered one locked to the mean field, and a disordered one consisting of effectively decoupled oscillators-at least so in the thermodynamic limit. In finite ensembles, in contrast, such clear separation fails: The mean field fluctuates due to finite-size effects and thereby induces order in the disordered group. This publication demonstrates this effect, similar to noise-induced…

We consider a social-type network of coupled phase oscillators. Such a network consists of an active core of mutually interacting elements, and of a flock of passive units, which follow the driving…

Finite-sized-induced transitions to synchrony in a population of phase oscillators coupled via a nonlinear mean field is reported on, which microscopically is equivalent to a hypernetwork organization of interactions and argues that a transition to synchronies occurs only for finite-size ensembles and disappears in the thermodynamic limit.

- PhysicsScientific reports

By virtue of the Ott-Antonsen ansatz for sine-coupled phase oscillators, analytically tractable equations are obtained for the case where both coupling and common noise are present, and a counter-intuitive effect of dispersion of the oscillators frequencies at synchrony is reported.
