PhET Simulation: Double Wells and Covalent Bonds
published by the PhET
With this PhET simulation, you can explore quantum bound states in double potential wells.  You can interactively change features such as the width, spacing, and height of the wells, and see the changes to the energy eigenstates and wave functions continuously.  Time-dependent probability densities and wave functions can be shown using a variety of representations, for both eigenstates and superposition states.  You can select between square and Coulomb potential wells.
