Recurrence phase shift in Fermi-Pasta-Ulam nonlinear dynamics

Devine, Natasha; Ankiewicz, Adrian; Genty, Goery; Dudley, John M; Akhmediev, Nail


We show that the dynamics of Fermi-Pasta-Ulam recurrence is associated with a nonlinear phase shift between initial and final states that are otherwise identical, after a full growth-return cycle. The properties of this phase shift are studied for the particular case of the self-focussing nonlinear Schrödinger equation, and we describe the magnitude of the phase shift in terms of the system parameters. This phase shift, accumulated during the nonlinear recurrence cycle, is a...[Show more]
