We study diffusion properties of an inertial Brownian motor moving on a ratchet substrate, ie, a periodic structure with broken reflection symmetry. The motor is driven by an unbiased …
The spreading of a cloud of independent Brownian particles typically proceeds more effectively at higher temperatures, as it derives from the commonly known Sutherland …

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 …
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 …

Variations of effective diffusion coefficient of polar molecules exposed to microwave electric fields in a surface potential are studied by solving coupled stochastic differential equations …

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 …
In this work we study the diffusion of non-interacting overdamped particles, moving on unbiased disordered correlated potentials, subjected to Gaussian white noise. We obtain an …

In this work we study analytically and numerically the transport properties of non-interacting active particles moving on a d-dimensional disordered medium. The disorder is modeled by …
This paper is devoted to the studies of the specific features of the simulation of the particle diffusion processes in space–periodic potentials using Langevin equations. Different …
