Multiple symmetry breaking induced by weak damping in the Fermi-Pasta-Ulam-Tsingou recurrence process
Guillaume Vanderhaegen, Pascal Szriftgiser, Alexandre Kudlinski +4
We show that even small dissipation can strongly affect the Fermi-Pasta-Ulam-Tsingou recurrence phenomenon. Taking the fully nonlinear stage of modulational instability as an exper…
Observation of the noise-driven thermalization of the Fermi-Pasta-Ulam-Tsingou recurrence in optical fibers
Guillaume Vanderhaegen, Pascal Szriftgiser, Alexandre Kudlinski +3
We report the observation of the thermalization of the Fermi-Pasta-Ulam-Tsingou recurrence process in optical fibers. We show the transition from a reversible regime to an irrevers…
Stochastic modulational instability in the nonlinear Schrödinger equation with colored random dispersion
Andrea Armaroli, Guillaume Dujardin, Alexandre Kudlinski +4
We study modulational instability (MI) in optical fibers with random group-velocity dispersion (GVD). We consider Gaussian and dichotomous colored stochastic processes. We resort t…
Separatrix crossing and symmetry breaking in NLSE-like systems due to forcing and damping
D. Eeltink, A. Armaroli, C. Luneau +3
We theoretically and experimentally examine the effect of forcing and damping on systems that can be described by the nonlinear Schrödinger equation (NLSE), by making use of the ph…
Stabilization of uni-directional water-wave trains over an uneven bottom
Andrea Armaroli, Alexis Gomel, Amin Chabchoub +2
We study the evolution of nonlinear surface gravity water-wave packets developing from modulational instability over an uneven bottom. A nonlinear Schrödinger equation (NLSE) with…
Time-reversal focusing of an expanding soliton gas in disordered replicas
A. Fratalocchi, A. Armaroli, S. Trillo
We investigate the properties of time reversibility of a soliton gas, originating from a dispersive regularization of a shock wave, as it propagates in a strongly disordered enviro…
