The influence of multi-dimensionality and off-diagonal non-Markovian friction coupling on coarse-grained dynamics
Henrik Kiefer, Cihan Ayaz, Benjamin A. Dalton +1
Coarse-graining complex molecular systems to lower-dimensional reaction coordinates is a powerful approach for capturing their effective dynamics. The generalized Langevin equation…
Analysis and Simulation of Generalized Langevin Equations with Non-Gaussian Orthogonal Forces
Henrik Kiefer, Benjamin J. A. Héry, Lucas Tepper +3
The generalized Langevin equation (GLE) is a useful framework for analyzing and modeling the dynamics of many-body systems in terms of low-dimensional reaction coordinates, with it…
Memory and Friction: From the Nanoscale to the Macroscale
Benjamin A. Dalton, Anton Klimek, Henrik Kiefer +5
Friction is a phenomenon that manifests across all spatial and temporal scales, from the molecular to the macroscopic scale. It describes the dissipation of energy from the motion…
Predictability Analysis and Prediction of Discrete Weather and Financial Time-Series Data with a Hamiltonian-Based Filter-Projection Approach
Henrik Kiefer, Denis Furtel, Cihan Ayaz +3
The generalized Langevin equation (GLE), derived by projection from a general many-body Hamiltonian, exactly describes the dynamics of an arbitrary coarse-grained variable in a com…
Effect of Frequency-Dependent Viscosity on Molecular Friction in Liquids
Henrik Kiefer, Domenico Vitali, Benjamin A. Dalton +2
The relation between the frequency-dependent friction of a molecule in a liquid and the hydrodynamic properties of the liquid is fundamental for molecular dynamics. We investigate…
