Understanding and modelling the dynamic behaviour of particulate systems has been a
major research focus worldwide for many years. Discrete particle simulation plays an …

We summarize procedures for producing'nanoemulsions' comprised of nanoscale droplets,
methods for controlling the droplet size distribution and composition, and interesting …

We have studied how two-and three-dimensional systems made up of particles interacting
with finite range, repulsive potentials jam (ie, develop a yield stress in a disordered state) at …

Cell migration is important in many biological processes, including embryonic development,
cancer metastasis and wound healing. In these tissues, a cell's motion is often strongly …

Hyperuniform states of matter are correlated systems that are characterized by an
anomalous suppression of long-wavelength (ie, large-length-scale) density fluctuations …

Amorphous materials as diverse as foams, emulsions, colloidal suspensions and granular
media can jam into a rigid, disordered state where they withstand finite shear stresses …

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 …

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 …

Shear thickening is a type of non-Newtonian behavior in which the stress required to shear a
fluid increases faster than linearly with shear rate. Many concentrated suspensions of …

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 …
