We explain the dynamics of cold atoms, initially trapped and cooled in a magneto-optic trap, in a monochromatic stationary standing electromagnetic wave field. In the large-detuning limit, the system is modeled as a nonlinear quantum pendulum. We show that the wavepacket evolution of the quantum particle probes parametric regimes in the quantum pendulum that support the classical period and quantum-mechanical revival and superrevival phenomena. Interestingly, complete reconstruction, in particular the parametric regime at quantum revival times, is independent of the potential height.
