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…
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…
Bidimensional measurements of photon statistics within a multimodal temporal framework
C. Hainaut, K. Ouahrouche, A. Rancon +5
Ultrafast imaging of photon statistics in two dimensions is a powerful tool for probing non-equilibrium and transient optical phenomena, yet it remains experimentally challenging d…

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…
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…
Perturbed Nonlinear Evolution of Optical Soliton Gases: Growth and Decay in Integrable Turbulence
Loic Fache, Francois Copie, Pierre Suret +1
We present optical fiber experiments investigating the perturbed, non-integrable evolution of soliton gases (SGs) under weak linear damping and gain. By measuring the amplitude and…
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…
Spontaneous modulational instability of elliptic periodic waves: the soliton condensate model

We use the spectral theory of soliton gas for the one-dimensional focusing nonlinear Schrödinger equation (fNLSE) to describe the statistically stationary and spatially homogeneous…
Manipulation of strongly interacting solitons in optical fiber experiments
Alexandre Mucci, Pierre Suret, François Copie +3
The model underlying physics of guiding light in single-mode fibers -- the one-dimensional nonlinear Schrödinger equation (NLSE), reveals a remarkable balance of the fiber dispersi…
Dissipation-driven emergence of a soliton condensate in a nonlinear electrical transmission line
Loic Fache, Hervé Damart, François Copie +6
We present an experimental study on the perturbed evolution of Korteweg-deVries soliton gases in a weakly dissipative nonlinear electrical transmission line. The system's dynamics…

Soliton gases represent large random soliton ensembles in physical systems that display integrable dynamics at the leading order. We report hydrodynamic experiments in which we inv…
Multisoliton interactions approximating the dynamics of breather solutions
D. S. Agafontsev, A. A. Gelash, S. Randoux +1
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…

The concept of soliton gas was introduced in 1971 by V. Zakharov as an infinite collection of weakly interacting solitons in the framework of Korteweg-de Vries (KdV) equation. In t…
Soliton refraction through an optical soliton gas
Pierre Suret, Martin Dufour, Giacomo Roberti +3
