A theoretical perspective is provided on the glass transition in molecular liquids at thermal
equilibrium, on the spatially heterogeneous and aging dynamics of disordered materials …

When a system jams, it undergoes a transition from a flowing to a rigid state. Despite this
important change in the dynamics, the internal structure of the system remains disordered in …

Understanding the characteristics of jammed particle packings provides basic insights into
the structure and bulk properties of crystals, glasses, and granular media and into selected …

The problem of finding the most efficient way to pack spheres has a long history, dating back
to the crystalline arrays conjectured by Kepler and the random geometries explored by …

Hard spheres are ubiquitous in condensed matter: they have been used as models for
liquids, crystals, colloidal systems, granular systems, and powders. Packings of hard …

In 1989, Sir Sam Edwards made the visionary proposition to treat jammed granular materials
using a volume ensemble of equiprobable jammed states in analogy to thermal equilibrium …

The remarkable kinetic slowdown experienced by liquids as they are cooled toward their
glass transition is not accompanied by any obvious structural change. Understanding the …

We use dynamic light scattering and computer simulations to study equilibrium dynamics
and dynamic heterogeneity in concentrated suspensions of colloidal hard spheres. Our …

Packing problems have been a source of fascination for millennia and their study has
produced a rich literature that spans numerous disciplines. Investigations of hard-particle …

We link the thermodynamics of colloidal suspensions to the statistics of regular and random
packings. Random close packing has defied a rigorous definition yet, in three dimensions …
