Dynamic Localization in Optical Lattices

We recapitulate the principle enabling the phenomenon of dynamic localization, and provide model calculations for ultracold atoms in driven optical lattices which indicate that the localization effect remains almost unaffected by interband transitions if the parameters are chosen carefully. In addition, we suggest to exploit the underlying quasienergy band collapse for coherently controlling the metal-insulator transition that occurs in the Harper model, as realized with quasiperiodic optical lattices.
