Wave packets

Non-stationary wave dynamics: electron twin-slit interference built up one detection at a time (with an animated view of the packet spreading), quantum revivals in an infinite well, Ehrenfest’s theorem in an anharmonic potential, and a phase-colored animation of double-well tunneling.
