This paper addresses the theoretical analysis of a fully discrete scheme for the one-dimensional time-dependent Schrödinger equation on unbounded domain. We first reduce the original problem into an initial-boundary value problem in a bounded domain by introducing a transparent boundary condition, t

✦ Synopsis
A finite-difference scheme is proposed for the one-dimensional time-dependent SchrSdinger equation. We introduce an artificial boundary condition to reduce the originM problem into an initial-boundary value problem in a finite-computational domain, and then construct a finitedifference scheme by the method of reduction of order to solve this reduced problem. This scheme has been proved to be uniquely solvable, unconditionally stable, and convergent. Some numericM examples are given to show the effectiveness of the scheme. (~) 2005 Elsevier Ltd.
