Polyelectrolytes in electric fields: Measuring the dynamical effective charge and effective friction

Kai Grass, Christian Holm

We use a coarse-grained molecular dynamics model to study the electrophoretic behaviour of flexible polyelectrolyte chains. We first characterize the static properties of the model…

Frequency dependent deformation of liquid crystal droplets in an external electric field

Günter K. Auernhammer, Jinyu Zhao, Beate Ullrich +1

Nematic drops suspended in the isotropic phase of the same substance were subjected to alternating electrical fields of varying frequency. The system was carefully kept in the isot…

Polymer desorption under pulling: a novel dichotomic phase transition

S. Bhattacharya, V. G. Rostiashvili, A. Milchev +1

We show that the structural properties and phase behavior of a self-avoiding polymer chain on adhesive substrate, subject to pulling at the chain end, can be obtained by means of a…

Simple and Robust Solver for the Poisson-Boltzmann Equation

M. Baptista, R. Schmitz, B. Duenweg

A variational approach is used to develop a robust numerical procedure for solving the nonlinear Poisson-Boltzmann equation. Following Maggs et al., we construct an appropriate con…

Progress in the Understanding of the Fluctuating Lattice Boltzmann Equation

Burkhard Duenweg, Ulf D. Schiller, Anthony J. C. Ladd

We give a brief account of the development of methods to include thermal fluctuations into lattice Boltzmann algorithms. Emphasis is put on our recent work (Phys. Rev. E 76, 036704…

Colloidal electrophoresis: Scaling analysis, Green-Kubo relation, and numerical results

B. Duenweg, V. Lobaskin, K. Seethalakshmy-Hariharan +1

We consider electrophoresis of a single charged colloidal particle in a finite box with periodic boundary conditions, where added counterions and salt ions ensure charge neutrality…

Dynamics of a stretched nonlinear polymer chain

M. Febbo, A. Milchev, V. Rostiashvili +2

We study the relaxation dynamics of a coarse-grained polymer chain at different degrees of stretching by both analytical means and numerical simulations. The macromolecule is model…

Computational study of (111) epitaxially strained ferroelectric perovskites BaTiO3 and PbTiO3

Riku Oja, Karen Johnston, Johannes Frantti +1

The phase transition behaviour of PbTiO3 and BaTiO3 under (111) epitaxial strain is investigated using density-functional theory calculations. From tensile strains of +0.015 to com…

P3M algorithm for dipolar interactions

Juan J. Cerda, V. Ballenegger, O. Lenz +1

An extension to the P3M algorithm for electrostatic interactions is presented, that allows to efficiently compute dipolar interactions in periodic boundary conditions. Theoretical…

Lattice Boltzmann simulations of soft matter systems

Burkhard Duenweg, Anthony J. C. Ladd

This article concerns numerical simulations of the dynamics of particles immersed in a continuum solvent. As prototypical systems, we consider colloidal dispersions of spherical pa…

Adsorption Kinetics of a Single Polymer on a Solid Plane

S. Bhattacharya, A. Milchev, V. G. Rostiashvili +2

We study analytically and by means of an off-lattice bead-spring dynamic Monte Carlo simulation model the adsorption kinetics of a single macromolecule on a structureless flat subs…

Direct measurements of hydrophobic slippage using double-focus fluorescence cross-correlation

Olga I. Vinogradova, Kaloian Koynov, Andreas Best +1

We report results of direct measurements of velocity profiles in a microchannel with hydrophobic and hydrophilic walls, using a new high precision method of double-focus spacial fl…
