SYNCHRONIZED CHAOS AND INTERMITTENT SYNCHRONIZATION

We propose a normal form of the bidirectionally coupled element model to illustrate the generation mechanism of synchronized chaos. We show that synchronized chaos can be generated via a local tangent bifurcati on and recovered by a global mechanism, namely successive-crises. We r eport an interesting phenomenon of intermittent synchronization. We sh ow that synchronized chaos still survives even when two dynamical equa tions are not exactly the same, and even with noise. As a non-numerica l demonstration, we provide a direct implementation of electronics in a single-chip device.
