Intermittent lag synchronization in a pair of coupled chaotic oscillators

The intermittent lag synchronization of two nonidentical symmetrically coup led Rossler systems is investigated numerically. This phenomenon orginates by intermittent bursts away from a principal lag synchronization regime, th at correspond to jumps of the system toward other lag configurations. The g lobal scenario of transitions toward a perfect lag synchronization regime m ay be tracked by the identification of the different lag configurations and the measure of the fraction of time spent by the system in each one of the m. The statistical properties of this intermittent behavior are described a nd compared with the ones of on-off intermittency.
