- Bound states in cylindrically symmetric potentials

One-dimensional bound states

Electron States in a 1D lattice

- This lets the user deal with a lattice of up to 12 sites, either a regular lattice, or with an irregularity
- The mouse can explore wave functions at various energies, seeing how each diverges, up or down.
- Will find and display all energies, Then will display whichever wave functions the user wishes.
- Excellent tool at a number of levels, especially for effect of impurities in semiconductors

Symmetric 3-Dimensional Bound States

- Has a wide variety of potentials - square well, lennard-jones, etc.
- Solves for energy states. Will display the radial wave function
- User may select angular momentum quantum numbers, l and m.
- Displays probability distribution in the form of dots, which quickly suggest the shape of the wave function
