On the Numerical Solution of the Time-Dependent Schroedinger Equation

Abstract

An algorithm for the numerical solution of the Schrödinger equation in the case of a time dependent potential is proposed. Our simple modification upgrades the well known method of Koonin while negligibly increasing the computing time. In the presented test the accuracy is enhanced by up to an order of magnitude.
