Abstract
In a coherent superposition of many discrete quantum states, each contributing state evolves independently in time. Nevertheless, for short times, the dynamics of such a quantum system is almost periodic with a period T 1 corresponding to the typical energy separation between neighboring eigenstates. However, for times larger than this characteristic time, this periodicity disappears and new features emerge1: At fractions of another characteristic time T 2 the system is again periodic, however now, with a period which is a fraction of T 1. In this note we present an analytical approach2 towards these so-called fractional revivals.
