    "abstract": "We discuss the behavior of fidelity for a classically chaotic quantum system\nin the metallic regime. We show the existence of a critical value of the\nperturbation below which the exponential decay of fidelity is determined by the\nwidth of the Breit-Wigner distribution and above which the quantum decay\nfollows the classical one which is ruled by the Lyapunov exponent. The\nindependence of the decay {\\it rate} from the perturbation strength derives\nfrom the similarity of the quantum and classical relaxation process inside the\nHeisenberg time scale.",
