Origin of Thermal Nonlinear Refraction in Alcohols Revealed by Spatial Self-Phase Modulation under Excitation at 1560 nm

Abstract We investigated the relationship between molecular structure and nonlinear thermal responses of alcohols with different numbers of carbon atoms in their main chains using spatial self-phase modulation experiments at 1560 nm. The studied materials included the following a...

Maximum entropy modeling of spin-glass behavior in random lasers

We investigate random-laser (RL) emission fluctuations using a Maximum Entropy (MaxEnt) framework. Experimental spectra across pump powers are binarized into spin-like variables, and a MaxEnt model is inferred from single-wavelength magnetizations and pairwise correlations. The r...
