Normal and anomalous diffusion of Brownian particles on disordered potentials

R Salgado-García - Physica A: Statistical Mechanics and its Applications, 2016 - Elsevier
In this work we study the transition from normal to anomalous diffusion of Brownian particles
on disordered potentials. The potential model consists of a series of “potential hills”(defined …

Noise-induced rectification in out-of-equilibrium structures

R Salgado-García - Physical Review E, 2019 - APS
We consider the motion of overdamped particles over random potentials subjected to a
Gaussian white noise and a time-dependent periodic external forcing. The random potential …

Scarce defects induce anomalous deterministic diffusion

M Hidalgo-Soria, R Salgado-García - arXiv preprint arXiv:1605.01768, 2016 - arxiv.org
We introduce a simple model of deterministic particles in weakly disordered media which
exhibits a transition from normal to anomalous diffusion. The model consists of a set of non …
