Brownian dynamics of chain polymers

Faraday Discussions of the Chemical Society, 1987
The effect of constrained bond lengths and angles on the Brownian dynamics of wormlike polymer chains is calculated analytically and compared with dynamical simulations. An analytical correspondence between constraints and internal friction is developed and illustrated. The approximate numerical evaluation of the constraint matrix and its correlations,

Brownian dynamics of hard spherocylinders

Physical Review E, 1994
A model of hard spherocylinders exhibiting Brownian dynamics in a solvent is investigated by Brownian dynamics simulations. Long-time translational and rotational self-diffusion coefficients are calculated in the disordered phase over the whole range of densities and a ratio p of total length to width ranging from 1 to 6. A simple analytical formula is

BROWNIAN DYNAMICS OF MICROTUBULES

Journal of Biomechanics, 2012
Thermal fluctuations of microtubules (MTs) and other cytoskeletal filaments govern to a great extent the complex rheological properties of the cytoskeleton in eukaryotic cells. In recent years, much effort has been put into capturing the dynamics of these fluctuations by means of analytical and numerical models, e.g.

The Dynamics of Interacting Brownian Particles

Journal of Physics A: Mathematical and General, 1975
Suspensions of microscopic particles in a liquid occur widely in nature and are important in many industrial processes. In very dilute suspensions, the particles can be regarded as effectively non-interacting; thus a particle can take up any position in, and diffuse through, the suspension without interference from other particles.

Dynamics of Brownian Motion

2023
Abstract The research on Brownian motion and electronic noise in the 1900s–20s raised further theoretical questions about noise: The interwar years witnessed the building of a theoretical regime for noise based on three approaches. Chapter 7 examines an approach in the time domain.

Algorithms for Brownian dynamics

Molecular Physics, 2003
We derive a class of efficient and stable algorithms of Brownian dynamics using a formula, derived by Suzuki, to express time-ordered operators. These algorithms are simpler than those derived by Helfand from Runge-Kutta algorithms and, like Helfand algorithms, can be combined with SHAKE to describe the Brownian dynamics of constrained systems.

Dynamics of Brownian Assembly

2001
In Chapter 2, we discussed the chemistry of the covalent bond—or intramolecular chemistry. In this chapter, we discuss intermolecular chemistry—the chemistry of molecule-molecule interactions. A few of the types of interactions from intermolecular chemistry are: solvation, molecular recognition, molecular transport, molecular self-organization (e.g ...

The dynamics of Brownian particles

Journal of Physics A: Mathematical and General, 1975
The recent result of Pusey (see ibid., vol.8, p.1433 (1975)) for the initial decay of the temporal correlation function of the Kth spatial Fourier component of particle number density in a dilute solution of Brownian particles is re-examined for the case where the friction coefficient is frequency dependent and given by a hydrodynamical model.
