    "abstract": "Kicked rotors with certain non-analytic potentials avoid dynamical\nlocalization and undergo a metal-insulator transition. We show that typical\nproperties of this transition are still present as the non-analyticity is\nprogressively smoothed out provided that the smoothing is less than a certain\nlimiting value. We have identified a smoothing dependent time scale such that\nfull dynamical localization is absent and the quantum momentum distribution\ndevelops power-law tails with anomalous decay exponents as in the case of a\nconductor at the metal-insulator transition. We discuss under what conditions\nthese findings may be verified experimentally by using ultra cold atoms\ntechniques. It is found that ultra-cold atoms can indeed be utilized for the\nexperimental investigation of the metal-insulator transition.",
