Jamming by shear
A broad class of disordered materials including foams, glassy molecular systems, colloids and granular materials can form jammed states. A jammed system can resist small stresses without deformingExpand

Entropy and temperature of a static granular assembly: an ab initio approach.
We construct a statistical framework for static assemblies of deformable grains which parallels that of equilibrium statistical mechanics but with a conservation principle based on the mechanicalExpand

Statistical mechanics framework for static granular matter.
The physical properties of granular materials have been extensively studied in recent years. So far, however, there exists no theoretical framework which can explain the observations in a unifiedExpand

Jamming in systems composed of frictionless ellipse-shaped particles.
We study numerically frictionless ellipse packings versus the aspect ratio alpha, and find that the jamming transition is fundamentally different from that for spherical particles. The normal modeExpand

The Statistical Physics of Athermal Materials
At the core of equilibrium statistical mechanics lies the notion of statistical ensembles: a collection of microstates, each occurring with a given a priori probability that depends on only a fewExpand

Jamming as a critical phenomenon: a field theory of zero-temperature grain packings.
A field theory of frictionless grain packings in two dimensions is shown to exhibit a zero-temperature critical point at a nonzero value of the packing fraction. The zero-temperature constraint ofExpand

Numerical test of the Edwards conjecture shows that all packings are equally probable at jamming
A decades-old proposal that all distinct packings are equally probable in granular media has gone unproven due to the sheer number of packings involved. Numerical simulation now demonstrates that itExpand

Protocol dependence of the jamming transition.
We propose a theoretical framework for predicting the protocol dependence of the jamming transition for frictionless spherical particles that interact via repulsive contact forces. We study isostaticExpand

An effective-medium theory approach to ordering in Cu-Au alloys
The authors present a new approach, based on the effective-medium theory of metallic cohesion, to the study of alloy phase stability. The efficiency and applicability of the method is demonstrated byExpand

Stress fluctuations in transient active networks.
Inspired by experiments on dynamic extensile gels of biofilaments and motors, we propose a model of a network of linear springs with kinetics consisting of growth at a prescribed rate, death after aExpand
