Spatio-temporal thermalization and adiabatic cooling of guided light waves

Lucas Zanaglia, Josselin Garnier, Iacopo Carusotto +3

We propose and theoretically characterize three-dimensional spatio-temporal thermalization of a continuous-wave classical light beam propagating along a multi-mode optical waveguid…

Bridging Rayleigh-Jeans and Bose-Einstein condensation of a guided fluid of light with positive and negative temperatures

Lucas Zanaglia, Josselin Garnier, Sergio Rica +5

We consider the free propagation geometry of a light beam (or fluid of light) in a multimode waveguide. As a result of the effective photon-photon interactions, the photon fluid th…

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…

Experimental observation of turbulent coherent structures in a superfluid of light

Aurélien Eloy, Omar Boughdad, Mathias Albert +4

We experimentally explore the rich variety of nonlinear coherent structures arising in a turbulent flow of superfluid light past an obstacle in an all-optical configuration. The di…

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…
