The Rectangular Well Eigenstate Superposition model displays the time
evolution of the position-space wave function in an infinite 2D rectangular
well using a superposition of energy eigenfunctions Ψn,m(x,y) with energy
eigenvalues En,m. This model is distributed as a ready-to-run (compiled) Java
archive. Double clicking the ejs_qm_Superposition2DRectangularWell. (in
