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 …

Amorphous solids, or glasses, are distinguished from crystalline solids by their lack of long-
range structural order. At the level of two-body structural correlations, glassformers show no …

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 rheology of suspensions of Brownian, or colloidal, particles (diameter d≲ 1 μ m) differs
markedly from that of larger grains (d≳ 50 μ m). Each of these two regimes has been …

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

The relation between atomistic chemical structure, molecular architecture, molecular weight,
and material properties is of basic concern in modern soft material science and includes …

We recently reviewed the experimental determination of the volume fraction, ϕ, of hard-
sphere colloids, and concluded that the absolute value of ϕ was unlikely to be known to …

We present a new adaptive resolution technique for efficient particle-based multiscale
molecular-dynamics simulations. The presented approach is tailor-made for molecular …

Hard-sphere colloids are popular as models for testing fundamental theories in condensed
matter and statistical physics, from crystal nucleation to the glass transition. A single …

We report a number of experiments, mainly rheological measurements, examining the
yielding behavior of colloidal glasses with hard-sphere interaction plus a short-range …
