We study reaction-diffusion processes with multi-species particles and hard-core interaction.
We add boundary driving to the system by means of external reservoirs which inject and …

We discuss particle diffusion in a spatially inhomogeneous medium. From the microscopic
viewpoint we consider independent particles randomly evolving on a lattice. We show that …

We study a system of particles which jump on the sites of the interval $[1, L] $ of ${\mathbb Z}
$. The density at the boundaries is kept fixed to simulate the action of mass reservoirs. The …

Usually, in a nonequilibrium setting, a current brings mass from the highest density regions
to the lowest density ones. Although rare, the opposite phenomenon (known as “uphill …

Uphill diffusions constitute an intriguing phenomenon reported in a series of numerical
simulations and experiments in which particles move from lower to higher density regions, at …

Uphill currents are observed when mass diffuses in the direction of the density gradient. We
study this phenomenon in stationary conditions in the framework of locally perturbed one …

Stimulated by experimental evidence in the field of solution-born thin films, we study the
morphology formation in a three state lattice system subjected to the evaporation of one …

We study the pedestrian escape from an obscure corridor using a lattice gas model with two
species of particles. One species, called passive, performs a symmetric random walk on the …

We consider point particles in a table made of two circular cavities connected by two
rectangular channels, forming a closed loop under periodic boundary conditions. In the first …

We study the deterministic dynamics of N point particles moving at a constant speed in a 2D
table made of two polygonal urns connected by an active rectangular channel, which …
