Classical light thermalization toward negative temperature equilibrium states in optical fibers and extension to the quantum regime
We report the observation of classical light thermalization to the negative temperature Rayleigh-Jeans (RJ) equilibrium states. We extend theoretically these equilibrium states to the Bose-Einstein quantum regime (BE) through the analysis of the thermodynamic properties.
