Fuzzy transition region in a one-dimensional coupled-stable-map lattice

A coupled-map lattice showing complex behavior in the presence of a fully negative Lyapunov spectrum is considered. A dynamical phase transition from "frozen" disorder to chaoticlike evolution upon changing diffusive coupling is studied in detail. Various indicators provide a coherent description of the scenario: the existence of a finite transition region characterized by an irregular alternancy of periodic and chaotic evolution.
