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…
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…
