Efficient simulation of Schrödinger equation with piecewise constant positive potential
arXiv:1512.01306
Abstract
In this paper we introduce a new method for the simulation of a weak solution of the Schrödinger-type equation where the potential is piecewise constant and positive. The method, called killing walk on spheres algorithm, combines the classical walk of spheres algorithm with killing that can be determined by using panharmonic measures.
