Random close packing as a dynamical phase transition

S Wilken, RE Guerra, D Levine, PM Chaikin - Physical review letters, 2021 - APS
Sphere packing is an ancient problem. The densest packing is known to be a face-centered
cubic (FCC) crystal, with space-filling fraction ϕ FCC= π/18≈ 0.74. The densest “random …

Experimental observations of marginal criticality in granular materials

Y Wang, J Shang, Y Jin… - Proceedings of the …, 2022 - National Acad Sciences
Two drastically different theories predict the marginal criticality of jamming. The full replica
symmetry breaking (fullRSB) theory predicts the power-law distributions of weak contact …

Hyperuniformity of maximally random jammed packings of hyperspheres across spatial dimensions

CE Maher, Y Jiao, S Torquato - Physical Review E, 2023 - APS
The maximally random jammed (MRJ) state is the most random (ie, disordered)
configuration of strictly jammed (mechanically rigid) nonoverlapping objects. MRJ packings …

X-ray 3D imaging–based microunderstanding of granular mixtures: Stiffness enhancement by adding small fractions of soft particles

K Taghizadeh, M Ruf, S Luding… - Proceedings of the …, 2023 - National Acad Sciences
This research focuses on performing ultrasound propagation measurements and micro-X-
ray computed tomography (µXRCT) imaging on prestressed granular packings prepared …

Characterization of void space, large-scale structure, and transport properties of maximally random jammed packings of superballs

CE Maher, FH Stillinger, S Torquato - Physical Review Materials, 2022 - APS
Dense, disordered packings of particles are useful models of low-temperature amorphous
phases of matter, biological systems, granular media, and colloidal systems. The study of …

Elastic criterion for shear-banding instability in amorphous solids

XJ Wang, YZ Lu, X Lu, JT Huo, YJ Wang, WH Wang… - Physical Review E, 2022 - APS
In amorphous solids, plastic flow is prone to localization into shear bands via an avalanche
of shear-transformation (ST) rearrangements of constituent atoms or particles. However …

Local stability of spheres via the convex hull and the radical Voronoi diagram

PK Morse, EI Corwin - Physical Review E, 2023 - APS
Jamming is an emergent phenomenon wherein the local stability of individual particles
percolates to form a globally rigid structure. However, the onset of rigidity does not imply that …

Simu-D: A simulator-descriptor suite for polymer-based systems under extreme conditions

M Herranz, D Martínez-Fernández, PM Ramos… - International journal of …, 2021 - mdpi.com
We present Simu-D, a software suite for the simulation and successive identification of local
structures of atomistic systems, based on polymers, under extreme conditions, in the bulk, on …

Structural principles in liquids and glasses: Bottom-up or top-down

T Egami, CW Ryu - Frontiers in Materials, 2022 - frontiersin.org
The conventional approach to elucidate the atomic structure of liquid and glass is to start
with local structural units made of several atoms, and to use them as building blocks to form …

Equilibrium states corresponding to targeted hyperuniform nonequilibrium pair statistics

H Wang, S Torquato - Soft matter, 2023 - pubs.rsc.org
The Zhang–Torquato conjecture [G. Zhang and S. Torquato, Phys. Rev. E, 2020, 101,
032124.] states that any realizable pair correlation function g2 (r) or structure factor S (k) of a …
