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…
