Abstract

In this paper we review some approaches that lead to deviations from the well known Brownian motion. We focus on the less explored enhanced diffusion for which the mean-squared displacement is superlinear in time. Such a behavior appears to be generic in various nonlinear Hamiltonian systems. We discuss the Lévy walk scheme that gives rise to such enhancement and calculate the corresponding propagators. An application to a family of one-dimensional maps is presented.
