When the momentum of a wave packet is graphed on a quantum carpet, it displays an intricate pattern. When the temporal evolution of this wave packet is graphed on quantum carpets, the wave packet expands, and the initial pattern is lost. However, after a certain period of time, the waveform contracts and returns to its original state, and the initial pattern is restored. This continues to occur with periodic regularity. Quantum revivals, the periodic expansion and contraction of wave packets, are responsible for the restoration of the pattern. Although quantum revivals are mathematically complex, they are simple and easy to visualize on quantum carpets, as patterns expanding and reforming. Thus, quantum carpets provide clear visual evidence of quantum revivals.
