Degree-preserving conservative processes and a unified approach for their hydrodynamics

Chiara Franceschini, Patrícia Gonçalves, Kohei Hayashi +1

We investigate a broad class of large-scale one-dimensional interacting systems characterized by a single conservation law and satisfying the "degree-preserving property". Under mi…

Duality for some models of epidemic spreading

Chiara Franceschini, Ellen Saada, Gunter M. Schütz +1

We examine the role of boundaries and the structure of nontrivial duality functions for three non conservative interacting particle systems in one dimension that model epidemic spr…

Non-equilibrium fluctuations for SEP() with open boundary

C. Franceschini, P. Gonçalves, M. Jara +1

We analyze the non-equilibrium fluctuations of the partial symmetric simple exclusion process, SEP(), which allows at most particles per site, and we put it in…

Large deviations and additivity principle for the open harmonic process

Gioia Carinci, Chiara Franceschini, Rouven Frassek +2

We consider the boundary driven harmonic model, i.e. the Markov process associated to the open integrable XXX chain with non-compact spins. Using the factorial moments we character…

Solvable stationary non equilibrium states

Gioia Carinci, Chiara Franceschini, Davide Gabrielli +2

We consider the one dimensional boundary driven harmonic model and its continuous version, both introduced in \cite{FGK}. By combining duality and integrability the authors of \cit…

Hard Rod Hydrodynamics and the Levy Chentsov Field

Pablo A. Ferrari, Chiara Franceschini, Dante G. E. Grevino +1

We study the hydrodynamics of the hard rod model proposed by Boldrighini, Dobrushin and Soukhov by describing the displacement of each quasiparticle with respect to the correspondi…

Orthogonal polynomial duality and unitary symmetries of multi--species ASEP and higher--spin vertex models via --bialgebra structure of higher rank quantum groups

Chiara Franceschini, Jeffrey Kuan, Zhengye Zhou

We propose a novel, general method to produce orthogonal polynomial dualities from the --bialgebra structure of Drinfeld--Jimbo quantum groups. The --structure allows for t…

Hydrodynamical behavior for the generalized symmetric exclusion with open boundary

Chiara Franceschini, Patrícia Gonçalves, Beatriz Salvador

We analyze the generalized symmetric exclusion process, which allows at most particles per site, and we put it in contact with stochastic reservoirs whose strength is regulated…

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…

q-Orthogonal dualities for asymmetric particle systems

Gioia Carinci, Chiara Franceschini, Wolter Groenevelt

We study a class of interacting particle systems with asymmetric interaction showing a self-duality property. The class includes the ASEP(), asymmetric exclusion process, with…

Orthogonal Dualities of Markov Processes and Unitary Symmetries

Gioia Carinci, Chiara Franceschini, Cristian Giardinà +2

We study self-duality for interacting particle systems, where the particles move as continuous time random walkers having either exclusion interaction or inclusion interaction. We…

Self-duality of Markov processes and intertwining functions

Chiara Franceschini, Cristian Giardinà, Wolter Groenevelt

We present a theorem which elucidates the connection between self-duality of Markov processes and representation theory of Lie algebras. In particular, we identify sufficient condi…

Stochastic Duality and Orthogonal Polynomials

Chiara Franceschini, Cristian Giardinà

For a series of Markov processes we prove stochastic duality relations with duality functions given by orthogonal polynomials. This means that expectations with respect to the orig…

Energy-exchange stochastic models for non-equilibrium

Chiara Franceschini, Cristian Giardina

Non-equilibrium steady states are subject to intense investigations but still poorly understood. For instance, the derivation of Fourier law in Hamiltonian systems is a problem tha…
