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…
Experimental observation of ballistic correlations in integrable turbulence
Elias Charnay, Adrien Escoubet, Francois Copie +4
Unequal-time correlation functions fundamentally characterize emergent statistical properties in complex systems, yet their direct measurement in experiments is challenging. We rep…
Observation of a generalized Gibbs ensemble in photonics
Alvise Bastianello, Alexey Tikan, Francois Copie +2
In generic classical and quantum many-body systems, where typically energy and particle number are the only conserved quantities, stationary states are described by thermal equilib…
Controlled manipulation of solitons in a recirculating fiber loop using external potentials
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…
The effect of discrete-time evolution on thermalisation in a lattice
Thomas Moorcroft, Alberto Amo, François Copie +3
Particles subject to weak contact interactions in a finite-size lattice tend to thermalise. The Hamiltonian evolution ensures energy conservation and the final temperature is fully…
