When the packing fraction is increased sufficiently, loose particulates jam to form a rigid
solid in which the constituents are no longer free to move. In typical granular materials and …

The transition from a crystalline material with long-range order to a glass-like disordered
structure has been observed in several metal alloys and minerals using experimental …

RANDOM packings of spheres serve as models for a variety of noncrystalline particulate and
molecular aggregates, some of which, for example the amorphous phases of metals and …

We explore the glassy dynamics of soft colloids using microgels and charged particles
interacting by steric and screened Coulomb interactions, respectively. In the supercooled …

Some liquids do not crystallize below the melting point, but instead enter into a supercooled
state and on cooling eventually become a glass at the glass-transition temperature. During …

We report x-ray photon correlation spectroscopy and diffusing wave spectroscopy studies of
depletion gels formed from nanoscale silica colloids in solutions of nonabsorbing polymer …

We study a colloidal suspension confined between two quasiparallel walls as a model
system for glass transitions in confined geometries. The suspension is a mixture of two …

Crystallization and vitrification are two different routes to form a solid. Normally these two
processes suppress each other, with the glass transition preventing crystallization at high …

Glasses, are amorphous solids, in the sense that they display elastic behaviour. In
crystalline solids, elasticity is associated with phonons, which are quantized vibrational …

We report experiments on hard-sphere colloidal glasses that show a type of shear banding
hitherto unobserved in soft glasses. We present a scenario that relates this to an instability …
