The analysis of models like kicked rotator in the case when one of the parameters of the model is varied with a frequency incommensurate with the frequency of the kicks showed that the diffusive time scale increases exponentially with the classical diffusion rate . This case corresponds to Anderson localization in 2-dimensional random potential. In the case when modulation is done with 2 frequencies the transition from localization to diffusion takes place in analogy with Anderson transition in 3d . However, here all computations are done with one-dimensional system, instead of 3-dimensional. This makes such approach very efficient numerically and allows to observe indeed the transition without renormgroup assumptions and also to determine the scaling exponents near transition. More recent investigations  of the case with larger number of frequencies allowed to study the Anderson transition in this model for effective dimension . The numerically obtained critical exponents were found to be different from the standard scaling relation () that can be related to a quasiperiodic nature of effective potential in directions.
