摘要：

A modified atomic version of the quantum delta-kicked rotor is considered. In contrast to previous studies, we do not eliminate the excited-state amplitude. This gives rise to a mixing of internal and translational atomic dynamics. A semiclassical argument suggests that this could conceivably result in momentum delocalization. However, our analysis shows that the added complexity fails to destroy dynamical localization.
