Comparison of different exact generalized Langevin equations with a non-linear potential of mean force and an observable-dependent mass and friction
Benjamin J. A. Héry, Lucas Tepper, Roland R. Netz
The Mori-Zwanzig projection formalism constitutes a powerful and robust framework for deriving equations of motion in terms of generalized Langevin equations (GLEs) for an arbitrar…

Non-equilibrium generalized Langevin equation for multi-dimensional observables
Benjamin J. A. Héry, Lucas Tepper, Andrea Guljas +4
The Mori-Zwanzig formalism is a powerful theoretical framework for deriving equations of motion for coarse-grained observables in the form of generalized Langevin equations (GLEs)…

Integrable fishnet circuits and Brownian solitons
Žiga Krajnik, Enej Ilievski, Tomaž Prosen +2
We introduce classical many-body dynamics on a one-dimensional lattice comprising local two-body maps arranged on discrete space-time mesh that serve as discretizations of Hamilton…
