Shown is the probability density followed by the real part of the wave function of a Gaussian wave packet passing a double slit.
The domain is discretized by 300x300 lattice points where the scattering domain is modelled by a nearest-neighbour finite difference scheme. For the time evolution the so-called Crank-Nicolson method was utilized, similar to what was done by Paul Nylander; see bugman123.com/Physics/index.html and be amazed by his incredible computer simulations. A similar, but faster, double-slit Mathematica code is further to be found on that page.
