Complex Langevin dynamics and supersymmetric quantum mechanics

open access: yesJournal of High Energy Physics, 2021
Using complex Langevin method we probe the possibility of dynamical supersymmetry breaking in supersymmetric quantum mechanics models with complex actions.

Intermediate dynamics between Newton and Langevin [PDF]

open access: yesPhysical Review E, 2006
A dynamics between Newton and Langevin formalisms is elucidated within the framework of the generalized Langevin equation. For thermal noise yielding a vanishing zero-frequency friction the corresponding non-Markovian Brownian dynamics exhibits anomalous behavior which is characterized by ballistic diffusion and accelerated transport.

An attempt toward the generalized Langevin dynamics simulation

open access: yesCondensed Matter Physics, 2008
An attempt to generalize the Langevin dynamics simulation method is presented based on the generalized Langevin theory of liquids, in which the dynamics of both solute and solvent is treated by the generalized Langevin equations, but the integration of ...

The bar-hinge motor: a synthetic protein design exploiting conformational switching to achieve directional motility

open access: yesNew Journal of Physics, 2019
One challenge to synthetic biology is to design functional machines from natural building blocks, from individual amino acids up to larger motifs such as the coiled coil.

Extension of the Langevin power curve analysis by separation per operational state [PDF]

open access: yesWind Energy Science
In the last few years, the dynamical characterization of the power output of a wind turbine by means of a Langevin equation has been well established. For this approach, temporally highly resolved measurements of wind speed and power output are used to ...

Covariant nonequilibrium thermodynamics from Ito-Langevin dynamics

open access: yesPhysical Review Research, 2022
Using the recently developed covariant Ito-Langevin dynamics, we develop a nonequilibrium thermodynamic theory for small systems coupled to multiplicative noises.

Low-dose CT Reconstruction Based on Deep Energy Models

open access: yesCT Lilun yu yingyong yanjiu, 2022
Reducing the dose of computed tomography (CT) is essential for reducing the radiation risk in clinical applications. With the rapid development and wide application of deep learning, it has brought new directions for the development of low-dose CT ...

Langevin Dynamics With General Kinetic Energies [PDF]

open access: yesMultiscale Modeling & Simulation, 2018
We study Langevin dynamics with a kinetic energy different from the standard, quadratic one in order to accelerate the sampling of Boltzmann-Gibbs distributions. In particular, this kinetic energy can be non-globally Lipschitz, which raises issues for the stability of discretizations of the associated Langevin dynamics.

Dynamics of topological defects in the noisy Kuramoto model in two dimensions

open access: yesFrontiers in Physics, 2022
We consider the two-dimensional (2D) noisy Kuramoto model of synchronization with short-range coupling and a Gaussian distribution of intrinsic frequencies, and investigate its ordering dynamics following a quench. We consider both underdamped (inertial)

Funnel control for Langevin dynamics

open access: yesAutomatica
We study tracking control for stochastic differential equations of Langevin type and describe a new conceptual approach to the sampling problem for those systems. The objective is to guarantee the evolution of the mean value in a prescribed performance funnel around a given sufficiently smooth reference signal.
