ABSTRACT:
The time duration of a scattering process in quantum mechanics can be
characterized  by the so called Wigner delay time. Statistical approach
to the scattering problems in mesoscopic physics is usually  based on
the random matrix theory (RMT). The application of the RMT is limited
however to the situations where there are no non-trivial energy or length
scales in the system. In this talk the opposite situation is
considered. Namely, the statistical properties of the Wigner delay times
are investigated for different models of disordered and chaotic systems
exhibiting diffusion or localization.Wigner delay time: beyond the Random Matrix Theory
