Abstract
We investigate the distribution of the resonance widths
(Γ) and Wigner delay times
(τW) for scattering from two-dimensional
systems in the diffusive regime. We obtain the forms of these
distributions (log-normal for large τW and small
Γ, and power law in the opposite case) for different
symmetry classes and show that they are determined by the
underlying diffusive classical dynamics. Our theoretical
arguments are supported by extensive numerical calculations.
