coupled structurally nonequivalent systems. We find two regimes of synchronization in
dependence on the coupling strength: creation of a lower dimensional chaotic state, and for
larger coupling a transition toward a stable periodic motion. We characterize this new state,
showing that it is associated with an abrupt transition in the Lyapunov spectrum. The
robustness of this state against noise is discussed, and the use of this dynamical property as …
