Quantum particle in a 2D box: probability density $|\psi|^2$ evolving as a superposition of eigenstates
This program numerically solves the time-dependent Schrodinger equation for a particle confined to a rectangular box with hard walls (infinite potential well). The stationary states are products of sine functions, and a general initial wave packet evolves as a superposition of these eigenstates with time-dependent phases. The simulation displays the probability density |psi(x,y,t)|^2 as a height field evolving in time.
