Description
Spontaneous synchronization is a cooperative phenomenon common in
nature which makes oscillators of different frequencies, if strongly
coupled, operate together with a single common frequency. Such
cooperative effects occur in physical and biological systems over length
and time scales of several orders of magnitude. Examples are: flashing
of fireflies, rhythmic applause in a concert hall, animal flocking
behavior, electrical power-grids, etc. The most celebrated model of
synchronization is the Kuramoto model, introduced in 1975, which is
simple enough to allow quite a detailed analytical treatment, at the
same time capturing several features of realistic systems. After
discussing the general dynamical and statistical features of
synchronization, I will present its out-of-equilibrium physical aspects
when uncorrelated Langevin noise is added to the model.
