Yield Stress Discontinuity in a Simple Glass
Fathollah Varnik, Oliver Henrich
Large scale molecular dynamics simulations are performed to study the steady state yielding dynamics of a well established simple glass. In contrast to the supercooled state, where…
Poisson-Bracket Approach to the Dynamics of Nematic Liquid Crystals. The Role of Spin Angular Momentum
H. Stark, T. C. Lubensky
Nematic liquid crystals are well modeled as a fluid of rigid rods. Starting from this model, we use a Poisson-bracket formalism to derive the equations governing the dynamics of ne…
Surmounting Barriers: The Benefit of Hydrodynamic Interactions
Christoph Lutz, Michael Reichert, Holger Stark +1
We experimentally and theoretically investigate the collective behavior of three colloidal particles that are driven by a constant force along a toroidal trap. Due to hydrodynamic…
Dynamical heterogeneities in an attraction driven colloidal glass
Antonio M. Puertas, Matthias Fuchs, Michael E. Cates
The dynamical heterogeneities (DH) in non-ergodic states of an attractive colloidal glass are studied, as a function of the waiting time. Whereas the fluid states close to vitrify…
Photon Channelling in Foams
Michael Schmiedeberg, MirFaez Miri, Holger Stark
Experiments by Gittings, Bandyopadhyay, and Durian [Europhys. Lett.\ \textbf{65}, 414 (2004)] demonstrate that light possesses a higher probability to propagate in the liquid phase…
Nonlinear rheology of dense colloidal dispersions: a phenomenological model and its connection to mode coupling theory
Matthias Fuchs, Matthias Ballauff
Rheological properties, especially 'shear-thinning', of dense colloidal dispersions are discussed on three different levels. A generalized phenomonological Maxwell model gives a br…
