Exact Charge, Current, and Velocity Fields of Interacting Korteweg-de Vries Solitons
Thibault Bonnemain, François Copie, Pierre Suret +1
Solitons in integrable systems exhibit a dual wave-particle character, yet their identification as individual objects becomes ambiguous during interactions, where they deform and d…
Diffraction of deep-water solitons
Filip Novkoski, Loïc Fache, Félicien Bonnefoy +6
Solitons are localized nonlinear wave packets that propagate without spreading because nonlinearity balances dispersion. Their robustness is well understood in effectively one-dime…

François Copie, Gino Biondini, Jeffrey Oregero +3
We report the first experimental observation of breather gases (BGs) in optics, realized in a recirculating fiber loop enabling virtually lossless propagation over km. Initi…

François Copie, Pierre Suret, Stéphane Randoux
Optical solitons are self-sustained wave packets that propagate without distortion due to a balance between dispersion and nonlinearity. Their unique stability underpins key photon…

Breather solutions are considered to be generally accepted models of rogue waves. However, breathers are not localized, while wavefields in nature can generally be considered as lo…
