    Abstract

    We consider the revival properties of quantum systems with an eigenspectrum E ? n, and compare them with the simplest member of this class - the infinite square well. In addition to having perfect revivals at integer multiples of the revival time t, these systems all enjoy perfect fractional revivals at quarterly intervals of t. A closer examination of the quantum evolution is performed for the Pöschel-Teller and Rosen-Morse potentials, and comparison is made with the infinite square well using quantum carpets.
