External noise synchronizes forced oscillators - art. no. 030901

Periodic pulsatile perturbation of nonlinear oscillators generates phase-lo cking, quasiperiodic. and chaotic responses. This work shows that the appli cation of external noise to ensembles of such forced systems can synchroniz e oscillations, even in regimes where neither the noise nor the periodic fo rcing, when applied alone, would lead to such a phenomenon.
