About universality of lifetime statistics in quantum chaotic scattering

The statistics of the resonance widths and the behavior of the survival probability is studied in a particular model of quantum chaotic scattering (a particle in a periodic potential subject to static and time-periodic forces) introduced earlier in Gluck et al. (Phys. Lett. A 249 (1998) 483; Phys. Rev. Lett. 82 (1999) 1534). The coarse-grained distribution of the resonance widths is shown to be in good agreement with the prediction of random matrix theory (RMT). The behavior of the survival probability shows, however, some deviation from RMT.
