Phys. Rev. Lett. 74, 118–121 (1995)Self-Organized Criticality and Synchronization in a Lattice Model of Integrate-and-Fire OscillatorsReceived 15 June 1994; published in the issue dated 2 January 1995 We introduce two coupled map lattice models with nonconservative interactions and a continuous nonlinear driving. Depending on both the degree of conservation and the convexity of the driving we find different behaviors, ranging from self-organized criticality, in the sense that the distribution of events (avalanches) obeys a power law, to a macroscopic synchronization of the population of oscillators, with avalanches of the size of the system. © 1994 The American Physical Society URL:
