Periodic Potential Lab - New Interactive Version

Periodic Potential Lab solves the time-independent Schroedinger Equation in a 1-D spatial potential variation. The user can interactively with a single click explore the consequences of different confinement potentials such as square well, harmonic oscillator, or Coulombic confinement etc. The dispersion can be viewed side-by-side with the confinement potential and the associated wavefunctions. The user can visualize the allowed and forbidden bands, plot the bands in a compact and an expanded zone, and compare the results against a simple effective mass parabolic band.
