Jamming by shear

- Dapeng Bi, J. Zhang, B. Chakraborty, R. Behringer
- Materials Science, Medicine
- Nature
- 1 December 2011

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 deforming… Expand

Entropy and temperature of a static granular assembly: an ab initio approach.

- S. Henkes, C. O'Hern, B. Chakraborty
- Physics, Medicine
- Physical review letters
- 19 January 2007

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 mechanical… Expand

Statistical mechanics framework for static granular matter.

- S. Henkes, B. Chakraborty
- Physics, Medicine
- Physical review. E, Statistical, nonlinear, and…
- 31 October 2008

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 unified… Expand

Jamming in systems composed of frictionless ellipse-shaped particles.

- M. Mailman, C. Schreck, C. O'Hern, B. Chakraborty
- Physics, Medicine
- Physical review letters
- 5 December 2008

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 mode… Expand

The Statistical Physics of Athermal Materials

- Dapeng Bi, S. Henkes, K. Daniels, B. Chakraborty
- Physics
- 7 April 2014

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 few… Expand

Jamming as a critical phenomenon: a field theory of zero-temperature grain packings.

- S. Henkes, B. Chakraborty
- Physics, Medicine
- Physical review letters
- 14 April 2005

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 of… Expand

Numerical test of the Edwards conjecture shows that all packings are equally probable at jamming

- Stefano Martiniani, K. J. Schrenk, K. Ramola, B. Chakraborty, D. Frenkel
- Physics, Mathematics
- 20 October 2016

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 it… Expand

Protocol dependence of the jamming transition.

- T. Bertrand, R. Behringer, B. Chakraborty, C. O'Hern, M. Shattuck
- Physics, Medicine
- Physical review. E
- 16 June 2015

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 isostatic… Expand

An effective-medium theory approach to ordering in Cu-Au alloys

- Zhigang Xi, B. Chakraborty, K. W. Jacobsen, J. Nørskov
- Physics
- 31 August 1992

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 by… Expand

- Physics, Medicine
- Soft matter
- 23 January 2019

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 a… Expand
