Abstract
We numerically investigate the critical properties of nonequilibrium continuous phase transitions in two-dimensional, synchronously updated lattices of coupled chaotic maps. A finite-size scaling analysis provides evidence for the existence of a new universality class, characterized by a correlation-length exponent , while the exponent ratios , , and the amplitude ratio are consistent with the 2D Ising universality class. The standard value of is recovered for asynchronous updating rules.
