Rydberg atomic wave packets have demonstrated striking classical
properties. In particular, the wave packets display regions in which they
evolve like classical atoms. However, between these regions the wave
packet is dispersed and its evolution departs from the classical model. In
these nonclassical regions, the wave packet can either be dispersed or
coalesced into a number of equally spaced sub-wave-packets. The regions in
which the sub-wave-packets appear have come to be known as fractional
revivals. This paper reports the observation of these fractional revivals
and discusses their implications.
