The physics of jamming for granular materials: a review

RP Behringer, B Chakraborty - Reports on Progress in Physics, 2018 - iopscience.iop.org
Granular materials consist of macroscopic grains, interacting via contact forces, and
unaffected by thermal fluctuations. They are one of a class systems that undergo jamming, ie …

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

S Martiniani, KJ Schrenk, K Ramola, B Chakraborty… - Nature physics, 2017 - nature.com
In the late 1980s, Sam Edwards proposed a possible statistical-mechanical framework to
describe the properties of disordered granular materials. A key assumption underlying the …

Characterization of maximally random jammed sphere packings. III. Transport and electromagnetic properties via correlation functions

MA Klatt, S Torquato - Physical Review E, 2018 - APS
In the first two papers of this series, we characterized the structure of maximally random
jammed (MRJ) sphere packings across length scales by computing a variety of different …

Stress response of granular systems

K Ramola, B Chakraborty - Journal of Statistical Physics, 2017 - Springer
We develop a framework for stress response in two dimensional granular media, with and
without friction, that respects vector force balance at the microscopic level. We introduce …

Scaling theory for the frictionless unjamming transition

K Ramola, B Chakraborty - Physical review letters, 2017 - APS
We develop a scaling theory of the unjamming transition of soft frictionless disks in two
dimensions by defining local areas, which can be uniquely assigned to each contact. These …

Tensor electromagnetism and emergent elasticity in jammed solids

JN Nampoothiri, M D'Eon, K Ramola, B Chakraborty… - Physical Review E, 2022 - APS
The theory of mechanical response and stress transmission in disordered, jammed solids
poses several open questions of how nonperiodic networks—apparently indistinguishable …

Timescale divergence at the shear jamming transition

HA Vinutha, K Ramola, B Chakraborty, S Sastry - Granular matter, 2020 - Springer
We find that in simulations of quasi-statically sheared frictional disks, the shear jamming
transition can be characterized by an abrupt jump in the number of force bearing contacts …

Multifunctional Granular Hydrogels for Tissue‐Specific Repair

RJ Almeida, A Fernandes, VM Gaspar… - Multifunctional …, 2022 - Wiley Online Library
Granular hydrogels represent an emerging class of intrinsically modular multimicrogel‐
based platforms with valuable features for therapeutics delivery, as well as exogenous and …

Singularities in Hessian element distributions of amorphous media

VV Krishnan, S Karmakar, K Ramola - Physical Review Research, 2020 - APS
We show that the distribution of elements H in the Hessian matrices associated with
amorphous materials exhibit singularities P (H)∼| H| γ with an exponent γ< 0, as| H|→ 0. We …

On the complexity of energy landscapes: algorithms and a direct test of the Edwards conjecture

S Martiniani - 2017 - repository.cam.ac.uk
When the states of a system can be described by the extrema of a high-dimensional
function, the characterisation of its complexity, ie the enumeration of the accessible stable …
