Schrodinger Equation Potential Well Solver
Introduction The goal was to be able to solve the one dimensional Schrodinger’s equation of a particle in a box with a custom potential. This was done by a numeric approach using the Verlet algorithm below. Followed by normalization. This one dimensional solution can easily be extended…
