Abstract

We propose combined method, based on using of both the conservative finite-difference scheme and non-conservative Rosenbrock method, for solving a linear or non-linear 1D Schrödinger equation. The computer simulation results, obtained by using of combined method, are compared with corresponding results obtained using the conservative finite-difference scheme or Rosenbrock method. For 2D nonlinear problem the proposed method can significantly increase a computer simulation performance due to eliminating of using an iterative process, which is necessary for the conservative finite-difference scheme realization. The efficiency of this combined method with artificial boundary conditions is demonstrated by numerical experiments.

Keywords
