Rayleigh-Jeans thermalization vs beam cleaning in multimode optical fibers

Kilian Baudin, Josselin Garnier, Adrien Fusaro +4

Classical nonlinear waves exhibit, as a general rule, an irreversible process of thermalization toward the Rayleigh-Jeans equilibrium distribution. On the other hand, several recen…

Observation of light thermalization to negative temperature Rayleigh-Jeans equilibrium states in multimode optical fibers

K. Baudin, J. Garnier, A. Fusaro +5

Although the temperature of a thermodynamic system is usually believed to be a positive quantity, under particular conditions, negative temperature equilibrium states are also poss…

Interplay of thermalization and strong disorder: Wave turbulence theory, numerical simulations, and experiments in multimode optical fibers

Nicolas Berti, Kilian Baudin, Adrien Fusaro +3

We address the problem of thermalization in the presence of a time-dependent disorder in the framework of the nonlinear Schrödinger (or Gross-Pitaevskii) equation with a random pot…

Weak Langmuir turbulence in disordered multimode optical fibers

Kilian Baudin, Josselin Garnier, Adrien Fusaro +3

We consider the propagation of temporally incoherent waves in multimode optical fibers (MMFs) in the framework of the multimode nonlinear Schrödinger (NLS) equation accounting for…

Incoherent localized structures and hidden coherent solitons from the gravitational instability of the Schrödinger-Poisson equation

Josselin Garnier, Kilian Baudin, Adrien Fusaro +1

The long-term behavior of a modulationally unstable conservative nonintegrable system is known to be characterized by the soliton turbulence self-organization process. We consider…

Coherent soliton states hidden in phase-space and stabilized by gravitational incoherent structures

Josselin Garnier, Kilian Baudin, Adrien Fusaro +1

We consider the problem of the formation of soliton states from a modulationally unstable initial condition in the framework of the Schrödinger-Poisson (or Newton-Schrödinger) equa…

Dissipation-enhanced collapse singularity of a nonlocal fluid of light in a hot atomic vapor

Pierre Azam, Adrien Fusaro, Quentin Fontaine +6

We study the out-of-equilibrium dynamics of a two-dimensional paraxial fluid of light using a near-resonant laser propagating through a hot atomic vapor. We observe a double shock-…

Energy and wave-action flows underlying Rayleigh-Jeans thermalization of optical waves propagating in a multimode fiber

K. Baudin, A. Fusaro, J. Garnier +6

The wave turbulence theory predicts that a conservative system of nonlinear waves can exhibit a process of condensation, which originates in the singularity of the Rayleigh-Jeans e…

Dramatic acceleration of wave condensation mediated by disorder in multimode fibers

Adrien Fusaro, Josselin Garnier, Katarzyna Krupa +2

Classical nonlinear waves exhibit a phenomenon of condensation that results from the natural irreversible process of thermalization, in analogy with the quantum Bose-Einstein conde…

Wave condensation with weak disorder versus beam self-cleaning in multimode fibers

J. Garnier, A. Fusaro, K. Baudin +4

Classical nonlinear random waves can exhibit a process of condensation. It originates in the singularity of the Rayleigh-Jeans equilibrium distribution and it is characterized by t…
