Abstract | We consider the large time behavior for
nonlinear Schr\"odinger--Langevin equation in one dimension for WKB-initial data with different density at left/right far fields. We
show that the momentum damping overwhelms the quantum dispersion. Thus, unlike those in scattering theory, the solution tends
to an asymptotic state determined by a porous media equation. More precisely, the total density tends pointwise to a nonlinear diffusion wave and the phase tends to a corresponding function.
