On a structure preserving closure of Langevin dynamics
Travis Leadbetter, Prashant K. Purohit, Celia Reina
Given a particle system obeying overdamped Langevin dynamics, we demonstrate that it is always possible to construct a thermodynamically consistent macroscopic model which obeys a…

Bridging statistical mechanics and thermodynamics away from equilibrium: a data-driven approach for learning internal variables and their dynamics
Weilun Qiu, Shenglin Huang, Celia Reina
Thermodynamics with internal variables is a common approach in continuum mechanics to model inelastic (i.e., non-equilibrium) material behavior. While this approach is computationa…

A statistical mechanics derivation and implementation of non-conservative phase field models for front propagation in elastic media
Travis Leadbetter, Prashant K. Purohit, Celia Reina
Over the past several decades, phase field modeling has been established as a standard simulation technique for mesoscopic science, allowing for seamless boundary tracking of movin…
