DIFFUSIVE TRANSPORT IN A ONE DIMENSIONAL DISORDERED POTENTIAL INVOLVING CORRELATIONS
This article deals with transport properties of one dimensional Brownian
diffusion under the influence of a correlated quenched random force,
distributed as a two-level Poisson process. We find in particular that large
time scaling laws of the position of the Brownian particle are analogous to the
uncorrelated case. We discuss also the probability distribution of the
stationary flux going through a sample between two prescribed concentrations,
which differs significantly from the uncorrelated case.Comment: 9 pages, figures are not include
