Abstract
The recurrence phenomena of an initially well-localized wave packet are studied in periodically driven power-law potentials. For our general study we divide the potentials in two kinds, namely tightly binding and loosely binding potentials. In the presence of an external periodically modulating force, these potentials may exhibit classical and quantum chaos. We show that in the dynamics of a quantum wave packet in the modulated power law potentials quantum recurrences occur at various time scales. We develop general analytical relations for these times and discuss their parametric dependence.
