Abstract:Synchronization phenomena are subject or intense research efforts in physical, biological, chemical, and social systems. The Kuramoto model is a paradigmatic framework to study synchronization phenomena. This model has been studied for many different distributions of natural frequencies and results are believed to be qualitatively independent of the specific distribution as long as it is symmetric and unimodal. Here we consider very similar model in which individual units are excitable units instead of oscillatory. The model can display a non-equilibrium transition depending on the form of the probability distribution.
