Soft-matter systems when driven out of equilibrium often give rise to structures that usually lie in between the macroscopic scale of the material and microscopic scale of its …
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 perform a quantitative analysis of Monte Carlo simulation results of phase separation in ternary blends upon evaporation of one component. Specifically, we calculate the average …
In this paper, we develop a detailed analysis of critical prewetting in the context of the two- dimensional Ising model. Namely, we consider a two-dimensional nearest-neighbor Ising …

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 …

We present a simulation study of the one-dimensional φ 4 lattice theory with long-range interactions decaying as an inverse power r−(1+ σ) of the intersite distance r, σ> 0. We …
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 …
