Quantum revivals are recurrent forms of wave packets [1] that, in the course of their evolution, return to their initial form after a certain "revival time". This Demonstration shows the propagation of a particle in a one-dimensional box of length 1 with Dirichlet boundary conditions. The coordinate runs on the horizontal axis and the vertical axis is . The probability density has interesting fractal properties [2] due to the wave function's self-interference resulting from the boundary conditions. Revivals of this type appear in many fields of physics.
