The arrangements of particles and forces in granular materials have a complex organization
on multiple spatial scales that range from local structures to mesoscale and system-wide …

Living systems provide a paradigmatic example of active soft matter. Cells and tissues
comprise viscoelastic materials that exert forces and can actively change shape. This …

Over the past two decades percolation theory has been used to explain and model a wide
variety of phenomena that are of industrial and scientific importance. Examples include …

Rigidity percolation (RP) occurs when mechanical stability emerges in disordered networks
as constraints or components are added. Here we discuss RP with structural correlations, an …

This paper investigates the transition between the solid and liquid phases of sheared
granular materials from the perspective of the contact network. Tools from persistent …

The classification of materials into insulators and conductors has been shaken up by the
discovery of topological insulators that conduct robustly at the edge but not in the bulk. In …

Dense suspensions are a prototype of fluid that can dynamically enhance their viscosity to
resist strong forcing. Recent work established that the key to a large viscosity increase …

While the large majority of theoretical and numerical studies of the jamming transition
consider athermal packings of purely repulsive spheres, real complex fluids and soft solids …

Jamming describes a transition from a flowing or liquid state to a solid or rigid state in a
loose assembly of particles such as grains or bubbles. In contrast, clogging describes the …

We use numerical simulations to study the effect of particle friction on suspension flows of
non-Brownian hard particles. By systematically varying the microscopic friction coefficient μ …
