Abstract We explore the universal features of quantum scattering systems for which the classical scattering is chaotic. We do so by comparing the semiclassical approach and the stochastic approach, exhibiting their mutual overlap and their individual limits of applicability. We investigate in particular predictions of both approaches for the average cross section, for the autocorrelation function of a pair of S-matrix elements, its Fourier transform, the Wigner time delay, and the distribution… CONTINUE READING
