title: Coherent manipulation of quantum delta-kicked dynamics: faster-than-classical anomalous diffusion.
abstract: Large transporting regular islands are found in the classical phase space of a modified kicked rotor system in which the kicking potential is reversed after every two kicks. The corresponding quantum system, for a variety of system parameters and over long time scales, is shown to display energy absorption that is significantly faster than that associated with the underlying classical anomalous diffusion. The results are of interest to areas of both quantum chaos and quantum control.
