✦ Synopsis


For the solution of the Schrodinger equation by finite difference methods on a grid of mesh points we introduce complex potentials at the points near the boundaries, which minimize the reflection of the waves by the boundaries. This procedure simulates a transparency for the waves through the boundaries. Test calculations in one dimension with Gaussian wave packets demonstrate the applicability of the method.
