Quantum revivals and fractality for the Schr\"odinger equation
Abstract
We investigate the behavior of the Schr\"odinger equation under the influence of potentials, focusing on its relationship to quantum revivals and fractality. Our findings reveal that the solution displays fractal behavior at irrational times, while exhibiting regularity similar to the initial data at rational times. These extend the results of Oskolkov O and Rodnianski R2 on the free Schr\"odinger evolution to the general case regarding potentials.
