Abstract
Abstract. Non-interacting brownian particles follows Langevin equations fullfiling
fluctuation–dissipation relation between friction and thermal noise. Under a
linear potential (constant force) Einstein found a relation between diffusion and
transport through mobility. In nonlinear potentials this prediction is only satisfied
within the limit of very large constant external forces. Moreover, other more interesting
behaviors do appear, such as: dispersionless transport, sorting, giant diffusion,
subdiffusion, superdiffusion, subtransport, etc. All these phenomena depend
on the characteristics of the nonlinear potential landscape: periodic or random,
the symmetries and boundary conditions. Moreover, the presence of transport is
the keystone of most of this phenomenology. In this review we present numerical
simulations of these facts and theoretical analysis when possible
