Description

Dynamic behavior of coupled chaotic oscillators is investigated. For small coupling, chaotic state undergoes a transition from spatially disordered phase to ordered phase with an orientation symmetry breaking. For large coupling a transition from fully synchronization to partial synchronization with translation symmetry breaking is observed. Two bifurcation branches, one inphase branch starting from synchronous chaos and the other antiphase branch bifurcated from spatially random chaos, are identified by varying coupling strength ε. Hysteresis, bistability and first-order-transitions between these two branches are observed. (author)
