Conformations, transverse fluctuations, and crossover dynamics of a semi-flexible chain in two dimensions

A Huang, A Bhattacharya, K Binder - The Journal of Chemical Physics, 2014 - pubs.aip.org
We present a unified scaling description for the dynamics of monomers of a semiflexible
chain under good solvent condition in the free draining limit. We consider both the cases …

Dynamics of single semiflexible polymers in dilute solution

A Nikoubashman, A Milchev, K Binder - The Journal of chemical …, 2016 - pubs.aip.org
We study the dynamics of a single semiflexible chain in solution using computer simulations,
where we systematically investigate the effect of excluded volume, chain stiffness, and …

Detailed dynamics of discrete Gaussian semiflexible chains with arbitrary stiffness along the contour

AR Tejedor, JR Tejedor, J Ramírez - The Journal of Chemical Physics, 2022 - pubs.aip.org
We revisit a model of semiflexible Gaussian chains proposed by Winkler et al., solve the
dynamics of the discrete description of the model, and derive exact algebraic expressions for …

Generalized Langevin equation for a tagged monomer in a Gaussian semiflexible polymer

X Durang, C Lim, JH Jeon - The Journal of Chemical Physics, 2024 - pubs.aip.org
In this study, we present a comprehensive analysis of the motion of a tagged monomer
within a Gaussian semiflexible polymer model. We carefully derived the generalized …

Irreversible dynamics of a continuum driven by active matter

JC Neu, SW Teitsworth - Physical Review E, 2024 - APS
We study the fluctuational behavior of overdamped elastic filaments (eg, strings or rods)
driven by active matter which induces irreversibility. The statistics of discrete normal modes …

Imperfect diffusion-controlled reactions for stochastic processes with memory

TV Mendes, T Guérin - Europhysics Letters, 2024 - iopscience.iop.org
Many physical processes are controlled by the time that a random walker needs to reach a
target. In many practical situations, such as reaction kinetics, this target is imperfect: multiple …

Long-term memory induced correction to Arrhenius law

A Barbier-Chebbah, O Bénichou, R Voituriez… - arxiv preprint arxiv …, 2024 - arxiv.org
The Kramers escape problem is a paradigmatic model for the kinetics of rare events, which
are usually characterized by Arrhenius law. So far, analytical approaches have failed to …

Target search kinetics for random walkers with memory

O Bénichou, T Guérin, N Levernier, R Voituriez - Target Search Problems, 2024 - Springer
In this chapter, we consider the problem of a non-Markovian random walker (displaying
memory effects) searching for a target. We review an approach that links the first passage …

Generalized Langevin equation formulation for anomalous diffusion in the Ising model at the critical temperature

W Zhong, D Panja, GT Barkema, RC Ball - Physical Review E, 2018 - APS
We consider the two-(2D) and three-dimensional (3D) Ising models on a square lattice at the
critical temperature T c, under Monte Carlo spin flip dynamics. The bulk magnetization and …
