Polyelectrolyte Bundles
H. J. Limbach, M. Sayar, C. Holm
Using extensive Molecular Dynamics simulations we study the behavior of polyelectrolytes with hydrophobic side chains, which are known to form cylindrical micelles in aqueous solut…
Screening of Spherical Colloids beyond Mean Field -- A Local Density Functional Approach
Marcia C. Barbosa, Markus Deserno, Christian Holm +1
We study the counterion distribution around a spherical macroion and its osmotic pressure in the framework of the recently developed Debye-H"uckel-Hole-Cavity (DHHC) theory. This i…
Localization and freezing of a Gaussian chain in a quenched random potential
Vakhtang G. Rostiashvili, Thomas A. Vilgis
The Gaussian chain in a quenched random potential (which is characterized by the disorder strength ) is investigated in the - dimensional space by the replicated variational…
Dynamics of a polymer in a quenched random medium: A Monte Carlo investigation
A. Milchev, V. G. Rostiashvili, T. A. Vilgis
We use an off - lattice bead - spring model of a self - avoiding polymer chain immersed in a 3-dimensional quenched random medium to study chain dynamics by means of a Monte - Carl…
Interaction of colloids with a nematic-isotropic interface
D. Andrienko, M. Tasinkevych, P. Patricio +1
The Landau-de Gennes free energy is used to calculate the interaction between long cylindrical colloids and the nematic-isotropic (NI) interface. This interaction has two contribut…
Twist-bend instability for toroidal DNA condensates
Igor M. Kulic, Denis Andrienko, Markus Deserno
We propose that semiflexible polymers in poor solvent collapse in two stages. The first stage is the well known formation of a dense toroidal aggregate. However, if the solvent is…
A new model for simulating colloidal dynamics
Vladimir Lobaskin, Burkhard Duenweg
We present a new hybrid lattice-Boltzmann and Langevin molecular dynamics scheme for simulating the dynamics of suspensions of spherical colloidal particles. The solvent is modeled…
Nonlinear alternating current responses of graded materials
J. P. Huang, L. Gao, K. W. Yu +1
When a composite of nonlinear particles suspended in a host medium is subjected to a sinusoidal electric field, the electrical response in the composite will generally consist of a…
Particle rearrangements during transitions between local minima of the potential energy landscape of a supercooled Lennard-Jones liquid
Michael Vogel, Burkhard Doliwa, Andreas Heuer +1
The potential energy landscape (PEL) of supercooled binary Lennard-Jones (BLJ) mixtures exhibits local minima, or inherent structures (IS), which are organized into meta-basins (MB…
Young's modulus of polyelectrolyte multilayers from microcapsule swelling
O. I. Vinogradova, D. Andrienko, V. V. Lulevich +2
We measure Young's modulus of a free polyelectrolyte multilayer film by studying osmotically induced swelling of polyelectrolyte multilayer microcapsules filled with the polyelectr…
Forces between elongated particles in a nematic colloid
D. Andrienko, M. Tasinkevych, P. Patricio +2
Using molecular dynamics (MD) simulations we study the interactions between elongated colloidal particles (length to breath ratio > 1) in a nematic host. The simulation results are…
DNA Spools under Tension
I. M. Kulic, H. Schiessel
DNA-spools, structures in which DNA is wrapped and helically coiled onto itself or onto a protein core are ubiquitous in nature. We develop a general theory describing the non-equi…
What does the potential energy landscape tell us about the dynamics of supercooled liquids and glasses?
Burkhard Doliwa, Andreas Heuer
For a model glass-former we demonstrate via computer simulations how macroscopic dynamic quantities can be inferred from a PEL analysis. The essential step is to consider whole sup…
Interaction potentials for soft and hard ellipsoids
R. Everaers, M. R. Ejtehadi
Using results from colloid science we derive interaction potentials for computer simulations of mixtures of soft or hard ellipsoids of arbitrary shape and size. Our results are in…
Equilibration of Long Chain Polymer Melts in Computer Simulations
Rolf Auhl, Ralf Everaers, Gary S. Grest +2
Several methods for preparing well equilibrated melts of long chains polymers are studied. We show that the standard method in which one starts with an ensemble of chains with the…
Elasticity of polyelectrolyte multilayer microcapsules
V. V. Lulevich, D. Andrienko, O. I. Vinogradova
We present a novel approach to probe elastic properties of polyelectrolyte multilayer microcapsules. The method is based on measurements of the capsule load-deformation curves with…
Boundary slip as a result of a prewetting transition
D. Andrienko, Burkhard Dünweg, Olga I. Vinogradova
Some fluids exhibit anomalously low friction when flowing against a certain solid wall. To recover the viscosity of a bulk fluid, slip at the wall is usually postulated. On a macro…
Modeling DNA Structure, Elasticity and Deformations at the Base-pair Level
Boris Mergell, Mohammad R. Ejtehadi, Ralf Everaers
We present a generic model for DNA at the base-pair level. We use a variant of the Gay-Berne potential to represent the stacking energy between neighboring base-pairs. The sugar-ph…
Phase Separation in Binary Fluid Mixtures with Continuously Ramped Temperature
M. E. Cates, J. Vollmer, A. Wagner +1
We consider the demixing of a binary fluid mixture, under gravity, which is steadily driven into a two phase region by slowly ramping the temperature. We assume, as a first approxi…
On the nature of long-range contributions to pair interactions between charged colloids in two dimensions
Vladimir Lobaskin, Matthias Brunner, Clemens Bechinger +1
We perform a detailed analysis of solutions of the inverse problem applied to experimentally measured two-dimensional radial distribution functions for highly charged latex dispers…
Chromatin dynamics: Nucleosomes go mobile through twist defects
I. M. Kulic, H. Schiessel
We study the spontaneous ''sliding'' of histone spools (nucleosomes) along DNA as a result of thermally activated single base pair twist defects. To this end we map the system onto…
Translational Diffusion of Polymer Chains with Excluded Volume and Hydrodynamic Interactions by Brownian Dynamics Simulation
Bo Liu, Burkhard Duenweg
Within Kirkwood theory, we study the translational diffusion coefficient of a single polymer chain in dilute solution, and focus on the small difference between the short--time Kir…
