FRACTAL AND DYNAMICAL PROPERTIES OF THE KICKED HARPER MODEL

Abstract
We review recent work on the so-called kicked Harper model, which can be viewed either as a model system in the framework of quantum chaos, or as a pulsed version of the Harper model, which has been thoroughly investigated in the context of magnetic field effects in solid state physics. In particular we describe its rich phase diagram, by means of both dynamical methods and multifractal analysis of the spectrum.
