Spatio-temporal equilibrium thermodynamics of guided optical waves at positive and negative temperatures
Lucas Zanaglia, Josselin Garnier, Claire Michel +5
Optical thermalization has been recently studied in the 2D spatial evolution of (quasi-)monochromatic light waves propagating in multimode waveguides. Here, we investigate the spat…
Irreversible thermalization vs reversible dynamics mediated by anomalous correlators: Wave turbulence theory and experiments in optical fibers
T. Torres, J. Garnier, L. Zanaglia +8
We theoretically and experimentally investigate spontaneous self-organization in a conservative (Hamiltonian) turbulent wave system, operating far from thermodynamic equilibrium. O…
Negative absolute temperature attractor in a dense photon gas
M. Ferraro, F. Mangini, K. Stefanska +7
Statistical mechanics permits to connect the macroscopic properties of matter with the laws governing the evolution of its microscopic constituents. Such an approach has been very…
Wave turbulence, thermalization and multimode locking in optical fibers
M. Ferraro, K. Baudin, M. Gervaziev +9
We present a comprehensive overview of recent advances in theory and experiments on complex light propagation phenomena in nonlinear multimode fibers. On the basis of the wave turb…
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…
