摘要：

We study the properties of eigenfunctions and quasi-energies in the kicked Harper model. The analysis of eigenfunctions clearly shows the transition from localized to delocalized states in the parameter region K < L. In the delocalized phase numerical evidence is given for the simultaneous presence of pure point, singular continuous and absolutely continuous spectrum.
