  • Title: Time shifts and correlations in synchronized chaos.
    Author: Blakely JN, Pruitt MW, Corron NJ.
    Journal: Chaos; 2008 Mar; 18(1):013117. PubMed ID: 18377068.
    Abstract:
    We introduce a new method for predicting characteristics of the synchronized state achieved by a wide class of unidirectional coupling schemes. Specifically, we derive a transfer function from the coupling model that provides estimates of the correlation between the drive and response waveforms, and of the time shift (i.e., lag or anticipation) of the synchronized state. To demonstrate the method, we apply it to a simulated system of coupled Rossler oscillators as well as to an experimental system of coupled chaotic electronic circuits. Finally, we show that the transfer function can be exploited to design novel coupling schemes that significantly improve the correlation and increase the maximum achievable time shift.
