Mean flow modelling in high-order nonlinear Schrödinger equations
Alexis Gomel, Corentin Montessuit, Andrea Armaroli +4
The evaluation and consideration of the mean flow in wave evolution equations are necessary for the accurate prediction of fluid particle trajectories under wave groups, with relev…
Two statistical regimes in the transition to filamentation
Alexis Gomel, Geoffrey Gaulier, Debbie Eeltink +2
We experimentally investigate fluctuations in the spectrum of ultrashort laser pulses propagating in air, close to the critical power for filamentation. Increasing the laser peak p…
Stabilization of unsteady nonlinear waves by phase space manipulation
Alexis Gomel, Amin Chabchoub, Maura Brunetti +3
We introduce a dynamic stabilization scheme universally applicable to unidirectional nonlinear coherent waves. By abruptly changing the waveguiding properties, the breathing of wav…
Testing Critical Slowing Down as a Bifurcation Indicator in a Low-dissipation Dynamical System
M. Marconi, C. Metayer, A. Acquaviva +6
We study a two-dimensional low-dissipation dynamical system with a control parameter that is swept linearly in time across a transcritical bifurcation. We investigate the relaxatio…
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…
