Compressibility and pressure correlations in isotropic solids and fluids
J. P. Wittmer, H. Xu, P. Polinsak +4
Presenting simple coarse-grained models of isotropic solids and fluids in , and dimensions we investigate the correlations of the instantaneous pressure and its ideal…
Density Functional approach to Nonlinear Rheology
J. Reinhardt, F. Weysser, J. M. Brader
We present a density functional based closure of the pair Smoluchowski equation for Brownian particles under shear flow. Given an equilibrium free energy functional as input the th…
Shear modulus of simulated glass-forming model systems: Effects of boundary condition, temperature and sampling time
J. P. Wittmer, H. Xu, P. Polińska +2
The shear modulus G of two glass-forming colloidal model systems in d=3 and d=2 dimensions is investigated by means of, respectively, molecular dynamics and Monte Carlo simulations…
Overshoots in stress strain curves: Colloid experiments and schematic mode coupling theory
Christian P. Amann, Miriam Siebenbürger, Matthias Krüger +3
The stress versus strain curves in dense colloidal dispersions under start-up shear flow are investigated combining experiments on model core-shell microgels, computer simulations…
Glass elasticity from particle trajectories
Christian L. Klix, Florian Ebert, Fabian Weysser +3
Using positional data from video-microscopy of a two-dimensional colloidal system and from simulations of hard discs we determine the wave-vector-dependent normal mode spring const…
Tagged-particle motion in glassy systems under shear: Comparison of mode coupling theory and Brownian Dynamics simulations
Matthias Krüger, Fabian Weysser, Matthias Fuchs
We study the dynamics of a tagged particle in a glassy system under shear. The recently developed integration through transients approach based on mode coupling theory, is continue…
Tests of mode-coupling theory in two dimensions
Fabian Weysser, David Hajnal
We analyze the glassy dynamics of a binary mixtures of hard disks in two dimensions. Predictions of the Mode-Coupling theory(MCT) are tested with extensive Brownian dynamics simula…
Nonlinear response of dense colloidal suspensions under oscillatory shear: Mode-coupling theory and FT-rheology experiments
J. M. Brader, M. Siebenbuerger, M. Ballauff +5
Using a combination of theory, experiment and simulation we investigate the nonlinear response of dense colloidal suspensions to large amplitude oscillatory shear flow. The time-de…
From Equilibrium to Steady-State Dynamics after Switch-On of Shear
Matthias Krüger, Fabian Weysser, Thomas Voigtmann
A relation between equilibrium, steady-state, and waiting-time dependent dynamical two-time correlation functions in dense glass-forming liquids subject to homogeneous steady shear…
Structural relaxation of polydisperse hard spheres: comparison of the mode-coupling theory to a Langevin dynamics simulation
F. Weysser, A. M. Puertas, M. Fuchs +1
We analyze the slow, glassy structural relaxation as measured through collective and tagged-particle density correlation functions obtained from Brownian dynamics simulations for a…
Hard discs under steady shear: comparison of Brownian dynamics simulations and mode coupling theory
O. Henrich, F. Weysser, M. E. Cates +1
Brownian dynamics simulations of bidisperse hard discs moving in two dimensions in a given steady and homogeneous shear flow are presented close to and above the glasstransition de…
