Lévy diffusion in thermal equilibrium — •Eric Lutz — Institut für Physik, Universität Augsburg, 86135 Augsburg

We show how anomalous Lévy diffusion can occur for systems coupled to a thermal bath of harmonic oscillators. The fluctuation-dissipation relation is satisfied and leads both to a natural truncation of the process and to an algebraically slow relaxation to thermal equilibrium.
