FIG. 7.

(Color online) Synchronized dynamics of bidirectionally coupled Lorenz oscillators in dependence on the coupling strength ε. Two critical values for intermittencies are ε_t = 6.7 and ε_c = 12. (a) Rates r_i and synchronization index γ. The behaviors of the rates and the durations of desynchronization events are different from coupled Rössler oscillators. (b) Relative frequencies of the desynchronization events of different durations (durations are measured in cycles of oscillations, i.e. in the number of iterations of the φ_x,i map, see Section II). Thick solid line represents the actual relative frequencies of the desynchronization events of different durations, while thin solid line represents the relative frequencies, which would be there under assumption of independent transitions. Unlike Fig. 6, short desynchronization events dominate the dynamics.
