Transition to synchrony in finite Kuramoto ensembles Synchronization – the adjustment of rhythms among coupled self oscillatory systems – is a fascinating dynamical phenomenon found in many biological social and technical systems. The present thesis deals with synchronization in finite ensembles of weakly coupled self sustained oscillators with distributed frequencies. The standard model for the description of this collective phenomenon is the Kuramoto model – partly due to its analytical tractability in the thermodynamic limit of infinitely many oscillators. Similar to a phase transition in the thermodynamic limit an order parameter indicates the transition from incoherence to a partially synchronized state. In the latter a part of the oscillators rotates at a common frequency. In the finite case fluctuations occur originating from the quenched noise of the finite natural frequency sample ...
