Schroedinger's Equation

Schroedinger's equation is numerically solved by calling an external subroutine from within Mathematica. By importing the Fortran subroutine (named SCHROED, which implements a Crank-Nicholson scheme) using InterCall, it is possible to do various experiments -- for example shooting a wave-packet at a potential barrier and watching an animation of the packet being mostly reflected but also partially tunnelling through the wall. The potential function V[x,t], required by the Fortran SCHROED routine, can be written as a Mathematica function which gives a lot of flexibility for interactive experimentation. This notebook demonstrates one such experiment.

InterCall must be purchased seperately
