The Peregrine soliton (PS) is widely regarded as a prototype nonlinear structure capturing properties of rogue waves that emerge in the nonlinear propagation of unidirectional wave trains. It has been recently demonstrated that the PS can emerge locally, as an asymptotic structure arising from the propagation of an arbitrary large decaying pulse, independently of its solitonic content. This mathematical discovery has changed the widely accepted paradigm of the solitonic nature of rogue waves by enabling the PS to emerge from partially radiative or even completely solitonless initial data. Pierre Suret, Université Lille, CNRS, France, and colleagues utilized a water tank experiment with a particular aim to control the point of the PS occurrence in space-time by imposing an appropriately chosen initial chirp.
Pierre Suret sits down with the Physical Review Journal Club to discuss he and his team's ability to engineer localized wave packets with a prescribed solitonic and radiative content. Showcasing he and his team's use of the proposed method of nonlinear spectral engineering to recreate robust to higher-order nonlinear effects, preceding the wave breaking dynamics, that are inevitable in realistic wave propagation conditions.
Pierre Suret will present data from the study, followed by a live question-and-answer session where all participant questions will be answered. This session will be moderated by Phys. Rev. Fluids Editorial Board Member Michelle DiBenedetto, University of Washington.
Registration is free and a recording of the event will be provided to all registrants.
