Ergodic properties of the harmonic process

Frank Redig, Berend van Tol

In this paper we study detailed fluctuation results for a class of non-equilibrium steady states. The main example is the boundary driven harmonic model \cite{frassek2022exact}. In…

Hydrodynamic limit of the symmetric exclusion process on complete Riemannian manifolds and principal bundles

Jonathan Junné, Frank Redig, Rik Versendaal

We prove that the hydrodynamic limit of the symmetric exclusion process (SEP) is a Fokker-Planck equation in the setting of Poisson random neighborhood graphs approximating a weigh…

Gaussian concentration, integral probability metrics, and coupling functionals for infinite lattice systems

J. -R. Chazottes, P. Collet, F. Redig

We develop a transport-entropy framework for Gaussian concentration inequalities on the infinite product space , where is a finite set, in which sensitivity is…

Non-equilibrium steady states with a spatial Markov structure

Frank Redig, Berend van Tol

We investigate the structure of non-equilibrium steady states (NESS) for a class of exactly solvable models in the setting of a chain with left and right reservoirs. Inspired by re…

Hydrodynamic limit and large deviations for run-and-tumble particles with mean-field switching rates

Elena Pulvirenti, Frank Redig, Hidde van Wiechen

In this paper, we study run-and-tumble particles moving on two copies of the discrete torus (referred to as layers), where the switching rate between layers depends on a mean-field…

Random walks in a field of soft traps and criticality for the dissipative Abelian Sandpile Model

Frank Redig, Ellen Saada, Berend van Tol

Motivated by the dissipative abelian sandpile model, we analyze the trajectories of a one-dimensional random walk in a landscape of soft traps. These traps, placed at increasing di…
