This webpage contains an interactive simulation that allows users to explore quantum bound states in double potential wells.  Users 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. Users can select between square and Coulomb potential wells. This simulations is also contained within the Quantum Bound States simulation.
This page also contains a teacher's guide for use with this simulation.
This page is part of a large and growing collection. It has been designed using principles from physics education research and refined based on student interviews.
