Phase locking transitions in arrays of coupled anharmonic oscillators

ORAL

Abstract

The Chaotic Dynamics of Coupled Oscillator arrays with cubic anharmonicity is studied. Our model includes damping terms and external time dependent forces. These Coupled oscillators are either phase-lock or behave chaotically or hyperchaotically, depending upon the magnitude of their inter-oscillator coupling strength and the frequency of the applied external force. The associated Lyapunov exponents are determined indicating the type of attractor, and phase diagrams are presented.
