Derivation of the timedependent propagator for the threedimensional Schrodinger equation with one point interaction
Abstract
An explicit formula for the timedependent propagator of the Schrodinger equation with one point interaction in three dimensions is given. The derivation is based on the inverse Laplace transformation applied to the corresponding resolvent.
