Computation of minimum action paths of the stochastic nonlinear Schrödinger equation with dissipation

Abstract

Using the geometric minimum action method, we compute minimizers of the Freidlin–Wentzell functional for the dissipative linear and nonlinear Schrödinger equation. For the particular case of transitions between solitary waves of different amplitudes, we discuss the relationship of the minimizer of the PDE model to the minimizer of a finite-dimensional reduction.
