Abstract
Diffusive and localization properties of wavepackets are numerically i nvestigated in quasi-one-dimensional disordered media described by a t ight-binding Hamiltonian with long-range random interactions. Scaling properties of the packet size and of the fluctuations of the steady-st ate distribution reveal interesting analogies and differences with the kicked rotator and one-dimensional localization.
