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…
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…
Shifting velocity of temperature extremes under climate change
Joan Rey, Guillaume Rohat, Marjorie Perroud +2
Rapid changes in climatic conditions threaten both socioeconomic and ecological systems, as these might not be able to adapt or to migrate at the same pace as that of global warmin…
