Switching interacting particle systems: scaling limits, uphill diffusion and boundary layer

S Floreani, C Giardinà, F Hollander, S Nandan… - Journal of Statistical …, 2022 - Springer
This paper considers three classes of interacting particle systems on Z: independent random
walks, the exclusion process, and the inclusion process. Particles are allowed to switch their …

An overview of emergent order in far-from-equilibrium driven systems: From kuramoto oscillators to rayleigh–bénard convection

A Chatterjee, N Mears, Y Yadati, GS Iannacchione - Entropy, 2020 - mdpi.com
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 …

Uphill in reaction-diffusion multi-species interacting particles systems

F Casini, C Giardina, C Vernia - Journal of Statistical Physics, 2023 - Springer
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 …

Fick and Fokker–Planck diffusion law in inhomogeneous media

D Andreucci, ENM Cirillo, M Colangeli… - Journal of Statistical …, 2019 - Springer
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 …

Quantitative analysis of phase formation and growth in ternary mixtures upon evaporation of one component

SA Muntean, VCE Kronberg, M Colangeli, A Muntean… - Physical Review E, 2022 - APS
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 …

Critical prewetting in the 2d Ising model

D Ioffe, S Ott, S Shlosman, Y Velenik - The Annals of Probability, 2022 - projecteuclid.org
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 in single and multi-species systems

M Colangeli, C Giberti, C Vernia - Journal of Physics A …, 2023 - iopscience.iop.org
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 …

Hydrodynamics and transport in the long-range-interacting φ 4 chain

S Iubini, S Lepri, S Ruffo - Journal of Statistical Mechanics …, 2022 - iopscience.iop.org
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 …

A lattice model for active--passive pedestrian dynamics: a quest for drafting effects

ENM Cirillo, M Colangeli, A Muntean… - arXiv preprint arXiv …, 2019 - arxiv.org
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 …

Deterministic model of battery, uphill currents, and nonequilibrium phase transitions

ENM Cirillo, M Colangeli, O Richardson, L Rondoni - Physical Review E, 2021 - APS
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 …
