Polymer chain in a quenched random medium: slow dynamics and ergodicity breaking
Gabriele Migliorini, Vakhtang G. Rostiashvili, Thomas A. Vilgis
The Langevin dynamics of a self - interacting chain embedded in a quenched random medium is investigated by making use of the generating functional method and one - loop (Hartree)…
Dynamical Properties of the Slithering Snake Algorithm: A numerical test of the activated reptation hypothesis
L. Mattioni, J. P. Wittmer, J. Baschnagel +2
The correlations in the motion of reptating polymers in their melt are investigated by means of kinetic Monte Carlo simulations of the three dimensional slithering snake version of…
Polyelectrolyte Multilayering on a Charged Sphere
Rene Messina, Christian Holm, Kurt Kremer
The adsorption of highly \textit{oppositely} charged flexible polyelectrolytes onto a charged spherical surface is investigated by means of Monte Carlo simulations in a fashion whi…
Effective macroion charge and stability of highly asymmetric electrolytes at various salt conditions
Vladimir Lobaskin, Khawla Qamhieh
We study electrostatic mechanisms of destabilization of highly asymmetric electrolytes. For this purpose, we perform primitive model Monte Carlo simulations of charged macroions im…
Heat Conduction and Long-Range Spatial Correlation in 1D Models
Xin Zhou, Mitsumasa Iwamoto
Heat conduction in one-dimensional (1D) systems is studied based on an analytical S-matrix method, which is developed in the mesoscopic electronic transport theory and molecular dy…
Properties of Poly (isoprene) - Model Building in the Melt and in Solution
Roland Faller, Dirk Reith
Properties of 1,4-\textit{trans} poly (isoprene) at ambient conditions are determined by simulations on two length scales based on two different models: a full-atomistic and a meso…
Integration Schemes for Dissipative Particle Dynamics Simulations: From Softly Interacting Systems Towards Hybrid Models
Ilpo Vattulainen, Mikko Karttunen, Gerhard Besold +1
We examine the performance of various commonly used integration schemes in dissipative particle dynamics simulations. We consider this issue using three different model systems, wh…
Sound damping in ferrofluids: Magnetically enhanced compressional viscosity
Hanns Walter Mueller, Yimin Jiang, Mario Liu
The damping of sound waves in magnetized ferrofluids is investigated and shown to be considerably higher than in the non-magnetized case. This fact may be interpreted as a field-en…
Reply to E.G.D. Cohen, L. Rondoni, Physica A 306 (2002) 117
Tamas Tel, Juergen Vollmer, Laszlo Matyas
In their paper Cohen and Rondoni severely question the physical relevance of studies of transport by means of multibaker maps and other classes of dynamics considering the motion o…
Shear induced instabilities in layered liquids
Guenter K. Auernhammer, Helmut R. Brand, Harald Pleiner
Motivated by the experimentally observed shear-induced destabilization and reorientation of smectic A like systems, we consider an extended formulation of smectic A hydrodynamics.…
Where the linearized Poisson-Boltzmann cell model fails: (II) the planar case as a prototype study
M. N. Tamashiro, H. Schiessel
The classical problem of two uniformly charged infinite planes in electrochemical equilibrium with an infinite monovalent salt reservoir is solved exactly at the mean-field nonline…
Where the linearized Poisson-Boltzmann cell model fails: (I) spurious phase separation in charged colloidal suspensions
M. N. Tamashiro, H. Schiessel
We perform a linearization of the Poisson-Boltzmann (PB) density functional for spherical Wigner-Seitz cells that yields Debye-Hückel-like equations agreeing asymptotically with th…

Burkhard Doliwa, Andreas Heuer
We study the relation of the potential energy landscape (PEL) topography to relaxation dynamics of a small model glass former of Lennard-Jones type. The mechanism under investigati…
Ferrofluids as thermal ratchets
Andreas Engel, Hanns Walter Mueller, Peter Reimann +1
Colloidal suspensions of ferromagnetic nano-particles, so-called ferrofluids, are shown to be suitable systems to demonstrate and investigate thermal ratchet behavior: By rectifyin…
