Characterizing far from equilibrium states of the one-dimensional nonlinear Schr{ö}dinger equation
Abhik Kumar Saha, Romain Dubessy
We use the mathematical toolbox of the inverse scattering transform to study quantitatively the number of solitons in far from equilibrium one-dimensional systems described by the…
