Spectral up- and downshifting of Akhmediev breathers under wind forcing
D. Eeltink, A. Lemoine, H. Branger +6
We experimentally and numerically investigate the effect of wind forcing on the spectral dynamics of Akhmediev breathers, a wave-type known to model the modulation instability. We…
Nonlinear stage of Benjamin-Feir instability in forced/damped deep water waves
Andrea Armaroli, Debbie Eeltink, Maura Brunetti +1
We study a three-wave truncation of a recently proposed damped/forced high-order nonlinear Schrödinger equation for deep-water gravity waves under the effect of wind and viscosity.…
Recurrence in the high-order nonlinear Schrödinger equation: a low dimensional analysis
Andrea Armaroli, Maura Brunetti, Jérôme Kasparian
We study a three-wave truncation of the high-order nonlinear Schrödinger equation for deepwater waves (HONLS, also named Dysthe equation). We validate our approach by comparing it…
