Signature of ballistic effects in disordered conductors — •Ville Uski and Bernhard Mehlig — Department of Physical Resource Theory, Chalmers University of Technology, SE-41296 Gothenburg

Statistical properties of energy levels, wave functions, and quantum-mechanical matrix elements in disordered conductors are usually calculated assuming diffusive electron dynamics. It has been pointed out that ballistic effects may, under certain circumstances, dominate diffusive contributions. We study the influence of such ballistic effects on the statistical properties of wave functions in quasi-one-dimensional disordered conductors. Our results support the view that ballistic effects – on length scales much smaller than the mean free path – can be significant in these systems.
