Phys. Rev. E 59, R2520–R2522 (1999)Synchronization of coupled systems with spatiotemporal chaos
We argue that the synchronization transition of stochastically coupled cellular automata, discovered recently by Morelli et al. [Phys. Rev. E 58, R8 (1998)], is generically in the directed percolation universality class. In particular this holds numerically for the specific example studied by these authors, in contrast to their claim. For real-valued systems with spatiotemporal chaos such as coupled map lattices, we claim that the synchronization transition is generically in the universality class of the Kardar-Parisi-Zhang equation with a nonlinear growth limiting term. © 1999 The American Physical Society URL:
