Abstract

Chaotic lag synchronization is a subtle dynamical phenomenon in which the states of two mutually coupled, nonidentical chaotic oscillators follow each other with a fixed time delay. We investigate to what extent lag synchronization can be observed in laboratory experiments. Our measurements indicate that due to the influence of noise, lag synchronization appears to occur intermittently in time. Numerical confirmation and a heuristic explanation to the observed intermittent behavior are given.
