We show the existence of a critical value of the perturbation below which the exponential decay of fidelity is determined by the width of the Breit-Wigner distribution and above which the quantum decay follows the classical one which is ruled by the Lyapunov exponent. The independence of the decay {\\it rate} from the perturbation strength derives from the similarity of the quantum and classical relaxation process inside the Heisenberg time scale.", "revisions": [ { "version": "v1", "updated": "2001-12-10T15:55:18.000Z" } ], "analyses": { "keywords": [ "classically chaotic systems", "quantum motion", "sensitivity", "heisenberg time scale", "classical relaxation process inside" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
