The seven (four in the demo) lowest-energy normalized eigenfunctions are available. They are chosen to be real, with sign conventions as shown in the following diagram:

The user chooses the phase and relative amplitude of the coefficients at t=0. The applet plots the initial normalized probability distribution and animates its time development.

Instructions for use

• Set the phase and relative amplitude of a coefficient by clicking and/or dragging in its circular control area (phase plane).
• A coefficient may be set to zero by clicking the button at the center of its circle.
