Fractional Revival of High Momentum Wave Packet In the Infinite Square Well
This animation shows the probability density of a high momentum Gaussian-shaped wave packet excited in the infinite square well potential.
The animation leads up to the 1/2 fractional revival, during which the quantum-mechanical wave function has split into two distinct sub-packets, traveling in opposite directions in the well.
More information on wave packets in the infinite square well can be found in the paper:
