Time scale separation in the low temperature East model: rigorous results

Autor: Paul Chleboun, Fabio Martinelli, Alessandra Faggionato

We consider the non-equilibrium dynamics of the East model, a linear chain of 0-1 spins evolving under a simple Glauber dynamics in the presence of a kinetic constraint which forbids flips of those spins whose left neighbour is 1. We focus on the gla

Filtration and flow in micro/nano-channels and traffic flow are examples of processes subject to blocking when the channel conveying the particles becomes too crowded. We propose here a concurrent flow model where particles enter a channel randomly.

Lagrangian phase transitions in nonequilibrium thermodynamic systems

Autor: A. De Sole, Giovanni Jona-Lasinio, Davide Gabrielli, Lorenzo Bertini, Claudio Landim

In previous papers we have introduced a natural nonequilibrium free energy by considering the functional describing the large fluctuations of stationary nonequilibrium states. While in equilibrium this functional is always convex, in nonequilibrium t

On entropy production in nonequilibrium systems

Autor: Amos Maritan, Robert Ziener, Haye Hinrichsen

In this paper we discuss the meaning of the Schnakenberg formula for entropy production in non-equilibrium systems. To this end we consider a non-equilibrium system as part of a larger isolated system which includes the environment. We prove that the

Boundary induced phase transition with stochastic entrance and exit

Autor: Mithun K. Mitra, Sakuntala Chatterjee

We study an open-chain totally asymmetric exclusion process (TASEP) with stochastic gates present at the two boundaries. The gating dynamics has been modeled with the physical system of ion-channel gating in mind. These gates can randomly switch betw

Stochastic interacting particle systems out of equilibrium

Autor: Lorenzo Bertini, Davide Gabrielli, Giovanni Jona-Lasinio, A. De Sole, Claudio Landim

This paper provides an introduction to some stochastic models of lattice gases out of equilibrium and a discussion of results of various kinds obtained in recent years. Although these models are different in their microscopic features, a unified pict

Understanding the Lévy ratchets in terms of Lévy jumps

Autor: S Risau-Gusman, Sebastián Bouzat, Santiago Ibanez

We investigate the overdamped dynamics of a particle in a spatially periodic potential with broken reflection symmetry and subject to the action of a symmetric white Lévy noise. The system (referred to as the Lévy ratchet) has been previously studi

The role of noise on the steady state distributions of phytoplankton populations

The spatio-temporal behaviour of total chlorophyll concentration is investigated in the middle of the Tyrrhenian Sea by using a stochastic approach. The study is based on a reaction-diffusion-taxis model, which is used to analyse the dynamics of five

Noise-induced resonance-like phenomena in InP crystals embedded in fluctuating electric fields

Autor: Bernardo Spagnolo, Nicola Pizzolato, D. Persano Adorno

Publikováno v: Journal of Statistical Mechanics: Theory and Experiment. 2016:054021

We explore and discuss the complex electron dynamics inside a low-doped n-type InP bulk embedded in a sub-THz electric field, fluctuating for the superimposition of an external source of Gaussian correlated noise. The results presented in this study
