A comprehensive review is presented of the physical behavior of yield stress materials in
soft condensed matter, which encompasses a broad range of materials from colloidal …

As one increases the concentration of a colloidal suspension, the system exhibits a dramatic
increase in viscosity. Beyond a certain concentration, the system is said to be a colloidal …

The simplicity of hard spheres as a model system is deceptive. Although the particles
interact solely through volume exclusion, that nevertheless suffices for a wealth of static and …

The rich and diverse dynamics of particle-based systems ultimately originates from the
coupling of their degrees of freedom via internal interactions. To arrive at a tractable …

Many fundamental issues in classical condensed matter physics can be addressed
experimentally using systems of individually visible mesoscopic particles playing the role of …

Steady and oscillatory rheology was utilized to study the mechanical response of colloidal
glasses and gels with particular emphasis in their yielding behaviour. We used a …

The depletion attraction, induced upon addition of a nonadsorbing polymer to a colloidal
solution, can lead to gel formation at sufficiently high polymer concentrations, which …

We report a large amount of experimental data on the stress overshoot phenomenon which
takes place during start-up shear flows in a simple yield stress fluid, namely a carbopol …

Elastoviscoplastic materials present a transition from a gel-like to a liquidlike state induced
by shearing: While the first is primarily elastic, the second is predominantly viscous. The …

Concentrated hard-sphere suspensions and glasses are investigated with rheometry,
confocal microscopy, and Brownian dynamics simulations during start-up shear, providing a …
