Gorin, T. and Martinez, D. F. and Schomerus, Henning (2007) Long-time signatures of short-time dynamics in decaying quantum-chaotic systems. Physical Review E, 75 (1). 016217. ISSN 1539-3755Full text not available from this repository.
We analyze the decay of classically chaotic quantum systems in the presence of fast ballistic escape routes on the Ehrenfest time scale. For a continuous excitation process, the form factor of the decay cross section deviates from the universal random-matrix result on the Heisenberg time scale, i.e., for times much larger than the time for ballistic escape. We derive an exact analytical description and compare our results with numerical simulations for a dynamical model.
