Universality of synchrony: Critical behavior in a discrete model of stochastic phase-coupled oscillators

Academic Article


  • We present the simplest discrete model to date that leads to synchronization of stochastic phase-coupled oscillators. In the mean field limit, the model exhibits a Hopf bifurcation and global oscillatory behavior as coupling crosses a critical value. When coupling between units is strictly local, the model undergoes a continuous phase transition which we characterize numerically using finite-size scaling analysis. In particular, the onset of global synchrony is marked by signatures of the XY universality class, including the appropriate classical exponents β and ν, a lower critical dimension dlc=2, and an upper critical dimension duc=4. © 2006 The American Physical Society.
