Learning non-stationary Langevin dynamics from stochastic observations of latent trajectories. [PDF]

open access: yesNat Commun, 2021
Langevin dynamics describe transient behavior of many complex systems, however, inferring Langevin equations from noisy data is challenging. The authors present an inference framework for non-stationary latent Langevin dynamics and test it on models of ...

Memory Corrections to Markovian Langevin Dynamics. [PDF]

open access: yesEntropy (Basel)
Analysis of non-Markovian systems and memory-induced phenomena poses an everlasting challenge in the realm of physics. As a paradigmatic example, we consider a classical Brownian particle of mass M subjected to an external force and exposed to correlated thermal fluctuations. We show that the recently developed approach to this system, in which its non-

Nonlinear Langevin dynamics via holography [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract In this work, we consider non-linear corrections to the Langevin effective theory of a heavy quark moving through a strongly coupled CFT plasma. In AdS/CFT, this system can be identified with that of a string stretched between the boundary and the horizon of an asymptotically AdS black brane solution.

Accurate sampling using Langevin dynamics [PDF]

open access: yesPhysical Review E, 2007
We show how to derive a simple integrator for the Langevin equation and illustrate how it is possible to check the accuracy of the obtained distribution on the fly, using the concept of effective energy introduced in a recent paper [J. Chem. Phys.

Fourier Acceleration of Langevin Molecular Dynamics [PDF]

open access: yesPhysical Review E, 2000
Fourier acceleration has been successfully applied to the simulation of lattice field theories for more than a decade. In this paper, we extend the method to the dynamics of discrete particles moving in continuum.

Classical Langevin Dynamics for Model Hamiltonians [PDF]

open access: yesphysica status solidi (b), 2002
We propose a scheme for extending the model Hamiltonian method developed originally for studying the equilibrium properties of complex perovskite systems to include Langevin dynamics. The extension is based on Zwanzig's treatment of nonlinear generalized

Inferring temporal dynamics from cross-sectional data using Langevin dynamics. [PDF]

open access: yesR Soc Open Sci, 2021
Cross-sectional studies are widely prevalent since they are more feasible to conduct compared with longitudinal studies. However, cross-sectional data lack the temporal information required to study the evolution of the underlying dynamics. This temporal

Supersymmetries in nonequilibrium Langevin dynamics [PDF]

open access: yesPhysical Review E, 2021
Stochastic phenomena are often described by Langevin equations, which serve as a mesoscopic model for microscopic dynamics. It is known since the work of Parisi and Sourlas that reversible (or equilibrium) dynamics present supersymmetries (SUSYs). These are revealed when the path-integral action is written as a function not only of the physical fields,
