Solvable stationary non equilibrium states

G Carinci, C Franceschini, D Gabrielli… - Journal of Statistical …, 2024 - Springer
We consider the one dimensional boundary driven harmonic model and its continuous
version, both introduced in (Frassek et al. in J Stat Phys 180: 135–171, 2020). By combining …

On a class of solvable stationary non equilibrium states for mass exchange models

M Capanna, D Gabrielli, D Tsagkarogiannis - Journal of Statistical Physics, 2024 - Springer
We consider a family of models having an arbitrary positive amount of mass on each site
and randomly exchanging an arbitrary amount of mass with nearest neighbor sites. We …

Non-equilibrium steady state of the symmetric exclusion process with reservoirs

S Floreani, AG Casanova - arXiv preprint arXiv:2307.02481, 2023 - arxiv.org
Consider the open symmetric exclusion process on a connected graph with vertexes in $[N-
1]:=\{1,\ldots, N-1\} $ where points $1 $ and $ N-1$ are connected, respectively, to a left …

The open harmonic process: non-equilibrium steady state, pressure, density large deviation and additivity principle

G Carinci, C Franceschini, R Frassek… - arXiv preprint arXiv …, 2023 - arxiv.org
We consider the boundary driven harmonic model, ie the Markov process associated to the
open integrable XXX chain with non-compact spins. Via integrability we show that it is …

Close-to-equilibrium heat capacity

F Khodabandehlou, C Maes - Journal of Physics A: Mathematical …, 2024 - iopscience.iop.org
Close to equilibrium, the excess heat governs the static fluctuations. We study the heat
capacity in that McLennan regime, ie in linear order around equilibrium, using an expression …

Duality for a boundary driven asymmetric model of energy transport

G Carinci, F Casini, C Franceschini - Journal of Physics A …, 2024 - iopscience.iop.org
We study the asymmetric brownian energy, a model of heat conduction defined on the one-
dimensional finite lattice with open boundaries. The system is shown to be dual to the …

Integrable boundaries for the q-Hahn process

R Frassek - Journal of Physics A: Mathematical and Theoretical, 2022 - iopscience.iop.org
Taking inspiration from the harmonic process with reservoirs introduced by Frassek,
Giardinà and Kurchan in (2020 J. Stat. Phys. 180 135–71), we propose integrable boundary …

Duality for some models of epidemic spreading

C Franceschini, E Saada, GM Schütz… - arXiv preprint arXiv …, 2024 - arxiv.org
We examine three non-conservative interacting particle systems in one dimension modeling
epidemic spreading: the diffusive contact process (DCP), a model that we introduce and call …

Intertwining and propagation of mixtures for generalized KMP models and harmonic models

C Giardinà, F Redig, B van Tol - arXiv preprint arXiv:2406.01160, 2024 - arxiv.org
We study a class of stochastic models of mass transport on discrete vertex set $ V $. For
these models, a one-parameter family of homogeneous product measures $\otimes_ {i\in …

[PDF][PDF] Duality for Markov processes: a Lie algebraic approach

C Giardina, F Redig - 2024 - diamweb.ewi.tudelft.nl
This book is about a systematic Lie algebraic approach to duality for Markov processes. In
this introduction, we explain in words what is duality, what are the fundamental concepts in …
