Return probability: Exponential versus Gaussian decay
F. M. Izrailev, A. Castaneda-Mendoza
We analyze, both analytically and numerically, the time-dependence of the return probability in closed systems of interacting particles. Main attention is paid to the interplay bet…

Entropy production and fidelity for quantum many-body systems with noise
F. M. Izrailev, A. Castaneda-Mendoza
We study dynamical properties of systems with many interacting Fermi-particles under the influence of static imperfections. Main attention is payed to the time dependence of the Sh…
