Query: Fractional revivals through R\'enyi uncertainty relations   We show that the R\'enyi uncertainty relations give a good description of the
dynamical behavior of wave packets and constitute a sound approach to revival
phenomena by analyzing three model systems: the simple harmonic oscillator, the
infinite square well, and the quantum bouncer. We prove the usefulness of
entropic uncertainty relations as a tool for identifying fractional revivals by
providing a comparison in different contexts with the usual Heisenberg
uncertainty relation and with the common approach in terms of the
autocorrelation function.
