Numerically solve Schrodinger's Wave Equation with various potentials for bound states and wave packets. Real Quantum Physics - suitable for a theory lab or demonstration in an introductory Quantum Mechanics course. Find bound states for Harmonic Oscillator, Square Well, Ammonia Maser, Hydrogen Atom, and Delta Function Potentials. Follow a wave packet as it hits a Step Barrier, Resonant Potential and Tunnel Barrier. Enter energy values for a bound state and see if the solution converges - real energy values accurate to better than 1%. Observe the Ramsauer-Townsend effect and a wave packet tunnel through a forbidden potential barrier.   Screenshots: 1) Home page with options 2) Harmonic Oscillator with 5 energy levels 3) Bound state potentials 4) Wave packet bouncing off of a step function potential 5) Wave packet potentials 6) Split two levels of an ammonia maser 7) Wave packet incident on a barrier 8) Wave packet after tunneling through barrier - right side amplified by magnifier
