[HTML][HTML] Cosh gradient systems and tilting

MA Peletier, A Schlichting - Nonlinear Analysis, 2023 - Elsevier
We review a class of gradient systems with dissipation potentials of hyperbolic-cosine type.
We show how such dissipation potentials emerge in large deviations of jump processes …

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 …

Anisothermal chemical reactions: Onsager–Machlup and macroscopic fluctuation theory

DRM Renger - Journal of Physics A: Mathematical and …, 2022 - iopscience.iop.org
We study a micro and macroscopic model for chemical reactions with feedback between
reactions and temperature of the solute. The first result concerns the quasipotential as the …
