Hydrodynamic limit of the directed exclusion process

Ellen Saada, Federico Sau, Assaf Shapira

We derive the Euler (hyperbolic) hydrodynamic limit for the directed exclusion process (DEP), a one-dimensional conservative interacting particle system that preserves particle-hol…

Tiny fluctuations of the averaging process around its degenerate steady state

Federico Sau

We analyze nonequilibrium fluctuations of the averaging process on , a continuous degenerate Gibbs sampler running over the edges of the discrete -dimen…

From quenched invariance principle to semigroup convergence with applications to exclusion processes

Alberto Chiarini, Simone Floreani, Federico Sau

Consider a random walk on in a translation-invariant and ergodic random environment and starting from the origin. In this short note, assuming that a quenched invari…

Spectral gap of the symmetric inclusion process

Seonwoo Kim, Federico Sau

We consider the symmetric inclusion process on a general finite graph. Our main result establishes universal upper and lower bounds for the spectral gap of this interacting particl…

Fractional kinetics equation from a Markovian system of interacting Bouchaud trap models

Alberto Chiarini, Simone Floreani, Federico Sau

We consider a partial exclusion process evolving on in a random trapping environment. In dimension , we derive the fractional kinetics equation \begin{equatio…

Cutoff for the Averaging process on the hypercube and complete bipartite graphs

Pietro Caputo, Matteo Quattropani, Federico Sau

We consider the averaging process on a graph, that is the evolution of a mass distribution undergoing repeated averages along the edges of the graph at the arrival times of indepen…

On the meeting of random walks on random DFA

Matteo Quattropani, Federico Sau

We consider two random walks evolving synchronously on a random out-regular graph of vertices with bounded out-degree , also known as a random Deterministic Finite Auto…

Scaling Limits of Random Walks, Harmonic Profiles, and Stationary Non-Equilibrium States in Lipschitz Domains

Lorenzo Dello Schiavo, Lorenzo Portinale, Federico Sau

We consider the open symmetric exclusion (SEP) and inclusion (SIP) processes on a bounded Lipschitz domain , with both fast and slow boundary. For the random walks on dual t…

Mixing of the Averaging process and its discrete dual on finite-dimensional geometries

Matteo Quattropani, Federico Sau

We analyze the -mixing of a generalization of the Averaging process introduced by Aldous. The process takes place on a growing sequence of graphs which we assume to be finite-…

Higher order hydrodynamics and equilibrium fluctuations of interacting particle systems

Joe P. Chen, Federico Sau

Motivated by the recent preprint [arXiv:2004.08412] by Ayala, Carinci, and Redig, we first provide a general framework for the study of scaling limits of higher order fields. Then,…

Symmetric inclusion process with slow boundary: hydrodynamics and hydrostatics

Chiara Franceschini, Patrícia Gonçalves, Federico Sau

We study the hydrodynamic and hydrostatic limits of the one-dimensional open symmetric inclusion process with slow boundary. Depending on the value of the parameter tuning the inte…

Orthogonal polynomial duality of boundary driven particle systems and non-equilibrium correlations

Simone Floreani, Frank Redig, Federico Sau

We consider symmetric partial exclusion and inclusion processes in a general graph in contact with reservoirs, where we allow both for edge disorder and well-chosen site disorder.…

Hydrodynamics for the partial exclusion process in random environment

Simone Floreani, Frank Redig, Federico Sau

In this paper, we introduce a random environment for the exclusion process in obtained by assigning a maximal occupancy to each site. This maximal occupancy is allow…

Symmetric simple exclusion process in dynamic environment: hydrodynamics

Frank Redig, Ellen Saada, Federico Sau

We consider the symmetric simple exclusion process in with quenched bounded dynamic random conductances and prove its hydrodynamic limit in path space. The main tool…

Stochastic duality and eigenfunctions

Frank Redig, Federico Sau

We start from the observation that, anytime two Markov generators share an eigenvalue, the function constructed from the product of the two eigenfunctions associated to this common…

Factorized duality, stationary product measures and generating functions

Frank Redig, Federico Sau

We find all factorized duality functions for a class of interacting particle systems. The functions we recover are self-duality functions for interacting particle systems such as z…

Generalized immediate exchange models and their symmetries

Frank Redig, Federico Sau

We reconsider the immediate exchange model and define a more general class of models where mass is split, exchanged and merged. We relate the splitting process to the symmetric inc…

Duality and stationary distributions of the "Immediate Exchange Model" and its generalizations

Bart Van Ginkel, Frank Redig, Federico Sau

We prove that the "Immediate Exchange Model" of econophysics has a discrete dual, where the duality functions are those connecting the Brownian Energy Process and the Symmetric Inc…
