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 …

The archetypal feature of a viscoplastic fluid is its yield stress: If the material is not sufficiently
stressed, it behaves like a solid, but once the yield stress is exceeded, the material flows like …

A consensus is emerging that discontinuous shear thickening (DST) in dense suspensions
marks a transition from a flow state where particles remain well separated by lubrication …

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 …

Even in simple geometries, many complex fluids display nontrivial flow fields, with regions
where shear is concentrated. The possibility for such shear banding has been known for …

High solid dispersions are soft materials made of colloidal or non-colloidal particles
dispersed at high volume fractions in a liquid matrix. They include hard sphere glasses …

In the last two decades, advances in synthetic, experimental and modeling/simulation
methodologies have considerably enhanced our understanding of colloidal suspension …

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 …

Nonequilibrium phase transitions are routinely observed in both natural and synthetic
systems. The ubiquity of these transitions highlights the conspicuous absence of a general …

Dense suspensions of particles are relevant to many applications and are a key platform for
developing a fundamental physics of out-of-equilibrium systems. They present challenging …
