We present a generalized Langevin equation (GLE) of motion that governs exactly the time evolution of phase-space observables in finite open systems described by classical …
Coarse-graining (CG) approaches are becoming essential tools in the study of complex systems because they can considerably speed up computer simulations, with the promise of …

The Mori--Zwanzig formalism is applied to derive an equation for the evolution of linear observables of the overdamped Langevin equation. To illustrate the resulting equation and …
Dual-resolution models which combine atomistic and coarse-grained details are usually built sequentially. First, the coarse-grained model is optimized and subsequently atomistic …
