Stability of Quantum Motion: Beyond Fermi-golden-rule and Lyapunov decay
arXiv:quant-ph/0309154 · doi:10.1103/PhysRevE.69.025201
Abstract
We study, analytically and numerically, the stability of quantum motion for a classically chaotic system. We show the existence of different regimes of fidelity decay which deviate from Fermi Golden rule and Lyapunov decay.
