Locally favoured structures and dynamic length scales in a simple glass-former
C. Patrick Royall, Walter Kob
We investigate the static and dynamic properties of a weakly polydisperse hard sphere system in the deeply supercooled state, i.e. at densities higher than that corresponding to th…
Effects of vertical confinement on gelation and sedimentation of colloids
Azaima Razali, Christopher J. Fullerton, Francesco Turci +3
We consider the sedimentation of a colloidal gel under confinement in the direction of gravity. The confinement allows us to compare directly experiments and computer simulations,…
Effect of Collisional Elasticity on the Bagnold Rheology of Sheared Frictionless Two Dimensional Disks
Daniel Vågberg, Peter Olsson, S. Teitel
We carry out constant volume simulations of steady-state, shear driven flow in a simple model of athermal, bidisperse, soft-core, frictionless disks in two dimensions, using a diss…
Structuring polymer gels via catalytic reactions
Virginie Hugouvieux, Walter Kob
We use computer simulations to investigate how a catalytic reaction in a polymer sol can induce the formation of a polymer gel. To this aim we consider a solution of homopolymers i…
Rearrangement zone around a crack tip in a double self-assembled transient network
Guillaume Foyart, Christian Ligoure, Serge Mora +1
We investigate the nucleation and propagation of cracks in self-assembled viscoelastic fluids, which are made of surfactant micelles reversibly linked by telechelic polymers. The m…
Evaluating linear response in active systems with no perturbing field
Grzegorz Szamel
We present a method for the evaluation of time-dependent linear response functions for systems of active Ornstein-Uhlenbeck particles from unperturbed simulations. The method is in…
The nonequilibrium glassy dynamics of self-propelled particles
Elijah Flenner, Grzegorz Szamel, Ludovic Berthier
We study the glassy dynamics taking place in dense assemblies of athermal active particles that are driven solely by a nonequilibrium self-propulsion mechanism. Active forces are m…
Small angle neutron scattering contrast variation reveals heterogeneities of interactions in protein gels
A Banc, C Charbonneau, M Dahesh +4
The structure of model gluten protein gels prepared in ethanol/water is investigated by small angle X-ray (SAXS) and neutrons (SANS) scattering. We show that gluten gels display ra…
RheoSpeckle: a new tool to investigate local flow and microscopic dynamics of soft matter under shear
N. Ali, DCD. Roux, L. Cipelletti +1
To investigate the interplay between microscopic dynamics and macroscopic rheology in soft matter, we couple a stress-controlled-rheometer equipped with a Couette cell to a light s…
A variational approach to the liquid-vapor phase transition for hardcore ions in the bulk and in nanopores
Bastien Loubet, Manoel Manghi, John Palmeri
We employ a field-theoretical variational approach to study the behavior of ionic solutions in the grand canonical ensemble. To describe properly the hardcore interactions between…
Interplay between viscosity and elasticity in freely expanding liquid sheets
Srishti Arora, Christian Ligoure, Laurence Ramos
We investigate the dynamics of freely expanding liquid sheets prepared with fluids with different rheological properties, (i) viscous fluids with a zero-shear viscosity in th…
A stress-controlled shear cell for small-angle light scattering and microscopy
S. Aime, L. Ramos, J. -M. Fromental +3
We develop and thoroughly test a stress-controlled, parallel plates shear cell that can be coupled to an optical microscope or a small angle light scattering setup, for simultaneou…
Space-resolved diffusing wave spectroscopy measurements of the macroscopic deformation and the microscopic dynamics in tensile strain tests
M. -Y. Nagazi, G. Brambilla, G. Meunier +3
We couple a laser-based, space-resolved dynamic light scattering apparatus to a universal testing machine for mechanical extensional tests. We perform simultaneous optical and mech…
Comment on "Constant stress and pressure rheology of colloidal suspensions"
A. Ikeda, L. Berthier, P. Sollich
This is a comment on the recent letter by Wang and Brady on "Constant stress and pressure rheology of colloidal suspensions", Phys. Rev. Lett. 115, 158301 (2015).
Tuning Pairwise Potential Can Control the Fragility of Glass-Forming Liquids: From Tetrahedral Network to Isotropic Soft Sphere Models
Misaki Ozawa, Kang Kim, Kunimasa Miyazaki
We perform molecular dynamics simulations for a silica glass former model proposed by Coslovich and Pastore (CP) over a wide range of densities. The density variation can be mapped…
Torque-Induced Rotational Dynamics in Polymers: Torsional Blobs and Thinning
Michiel Laleman, Marco Baiesi, Boris P. Belotserkovskii +3
By using the blob theory and computer simulations, we investigate the properties of a linear polymer performing a stationary rotational motion around a long impenetrable rod. In pa…
