Unifying Plasticity in Ordered and Disordered Matter using Topological and Geometrical Descriptors
Xin Wang, Yang Xu, Jin Shang +5
Identifying the regions responsible for plastic flow in amorphous solids remains an open problem, since structural disorder seems to prevent the direct application of concepts such…
Torque Hyperuniformity in Frictional Granular Matter - Theory and Experiments
Jin Shang, Jie Zhang, Itamar Procaccia
A question of some fundamental importance is whether a given assembly of frictional granules (say sand or powder) will exhibit stress autocorrelations with long-range anisotropic d…
Experimental Confirmation of Hyperuniformity of torque fluctuations in Frictional Matter
Jin Shang, Jie Zhang, Itamar Procaccia
A recent purely theoretical prediction stated that in frictional granular packings, mechanical balance and material isotropy constrain the stress auto-correlation matrix to be full…
Topological defects govern plasticity and shear band formation in two-dimensional amorphous solids
Xin Wang, Jin Shang, Yujie Wang +2
Understanding the fundamental mechanisms behind plastic instabilities and shear band formation in amorphous media under applied deformation remains a long-standing challenge. Lever…
Jamming as a topological satisfiability transition with contact number hyperuniformity and criticality
Jin Shang, Yinqiao Wang, Deng Pan +2
The jamming transition between flow and amorphous-solid states exhibits paradoxical properties characterized by hyperuniformity (suppressed spatial fluctuations) and criticality (h…
Power Spectra of Velocity Fluctuations in Granular Heap Flow
ShuChang Yu, Jin Shang, YangRui Chen +5
This study used Speckle Visibility Spectroscopy to examine velocity fluctuations in a three-dimensional granular heap flow, where the mean velocity profile consists of a fast-flow…
Stress-stress correlations in two-dimensional amorphous and crystalline solids
Jimin Bai, Long-Zhou Huang, Jin Shang +3
Stress-stress correlations in crystalline solids with long-range order can be straightforwardly derived using elasticity theory. In contrast, the `emergent elasticity' of amorphous…
The yielding of granular matter is marginally stable and critical
Jin Shang, Yinqiao Wang, Yuliang Jin +1
The mechanical yield of dense granular materials is a fascinating rheological phenomenon, beyond which stress no longer increases with strain at a sufficiently large deformation. U…
Experimental observations of marginal criticality in granular materials
Yinqiao Wang, Jin Shang, Yuliang Jin +1
Two drastically different theories predict the marginal criticality of jamming. The full replica symmetry breaking (fullRSB) theory [1-4] predicts the power-law distributions of we…
Contact force measurements and local anisotropy in ellipses and disks
Yinqiao Wang, Jin Shang, Yujie Wang +1
Experimental measurements of contact forces are limited to spheres and disks in three and two dimensions, making the evaluation of the shape effect and universality of force distri…
Disorder-induced vibrational anomalies from crystalline to amorphous solids
Ling Zhang, Yinqiao Wang, Yangrui Chen +8
The origin of boson peak -- an excess of density of states over Debye's model in glassy solids -- is still under intense debate, among which some theories and experiments suggest t…
Critical behaviors of jamming in cyclically sheared frictional hard granular particles
Aile Sun, Yinqiao Wang, Yangrui Chen +5
In stark contrast to the jamming of frictionless hard-sphere (hard-disk if in two dimensions) packings, the critical jamming of frictional packings is much more elusive and still u…
