Jump processes as generalized gradient flows

MA Peletier, R Rossi, G Savaré, O Tse - Calculus of Variations and Partial …, 2022 - Springer
We have created a functional framework for a class of non-metric gradient systems. The
state space is a space of nonnegative measures, and the class of systems includes the …

Role of current fluctuations in nonreversible samplers

F Coghi, R Chetrite, H Touchette - Physical Review E, 2021 - APS
It is known that the distribution of nonreversible Markov processes breaking the detailed
balance condition converges faster to the stationary distribution compared to reversible …

Information geometry of dynamics on graphs and hypergraphs

TJ Kobayashi, D Loutchko, A Kamimura… - Information …, 2024 - Springer
We introduce a new information-geometric structure associated with the dynamics on
discrete objects such as graphs and hypergraphs. The presented setup consists of two …

Variational structures beyond gradient flows: a macroscopic fluctuation-theory perspective

RIA Patterson, DRM Renger, U Sharma - Journal of Statistical Physics, 2024 - Springer
Macroscopic equations arising out of stochastic particle systems in detailed balance (called
dissipative systems or gradient flows) have a natural variational structure, which can be …

Non-reversible processes: GENERIC, hypocoercivity and fluctuations

MH Duong, M Ottobre - Nonlinearity, 2023 - iopscience.iop.org
We consider two approaches to study non-reversible Markov processes, namely the
hypocoercivity theory and general equations for non-equilibrium reversible–irreversible …

Fast Reaction Limits via -Convergence of the Flux Rate Functional

MA Peletier, DRM Renger - Journal of Dynamics and Differential Equations, 2023 - Springer
We study the convergence of a sequence of evolution equations for measures supported on
the nodes of a graph. The evolution equations themselves can be interpreted as the forward …

[PDF][PDF] Mean-field limits and beyond: Large deviations for singular interacting diffusions and variational convergence for population dynamics

J Hoeksema - 2023 - research.tue.nl
This thesis consists of two parts, both focusing on mean-field limits for interacting particle
systems, which describe the macroscopic behaviour of the system as the number of particles …

GENERIC framework for reactive fluid flows

A Zafferi, D Peschka, M Thomas - ZAMM‐Journal of Applied …, 2023 - Wiley Online Library
We describe reactive fluid flows in terms of the formalism General Equation for Non‐
Equilibrium Reversible‐Irreversible Coupling also known as GENERIC. We present the …

Untangling dissipative and Hamiltonian effects in bulk and boundary-driven systems

DRM Renger, U Sharma - Physical Review E, 2023 - APS
Using the theory of large deviations, macroscopic fluctuation theory provides a framework to
understand the behavior of nonequilibrium dynamics and steady states in diffusive systems …
