Visscher's method for 2d numerical solution of Schroedingers eqn.

  1. Jun 24, 2010 #1
    Does anyone here have a very good description & or a working demo+source code of his method for solving the T.D. schroedinger eqn. on a 2d lattice? Theres a nice demo here http://www.asc.tuwien.ac.at/~juengel/simulations/schroedinger/Visscher2D/Visscher2D.html" [Broken]. I've coded my own 2d system as an extention of an already fairly slow 1d one & now realise i need a more stable solver!
    If there is a free online source for his paper (P.B. Visscher: A fast explicit algorithm for the time dependent Schrödinger equation, Computers in Physics 5 (6), 596-598 (1991)) please post the link here!

    TIA
    Rob.
