Analytic theory of shear localization in amorphous solids confined by Couette geometry
Yang Fu, Yuliang Jin, Itamar Procaccia
``Couette geometry'' refers to two concentric rings in 2-dimensions (or cylinders in 3-dimensions with a medium in between). Typically the inner and outer rings (or cylinders) rota…
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…
Dipole-Induced Transition in 3-Dimensions
Itamar Procaccia, Tuhin Samanta
The Kosterlitz-Thouless and the Hexatic phase transitions are celebrated examples of dipole (vortex, dislocation) induced transitions in condensed matter physics. For very clear re…
Aging of amorphous materials under cyclic strain
Dor Shohat, Paul Baconnier, Itamar Procaccia +2
Amorphous materials driven away from equilibrium display a diverse repertoire of complex, history-dependent behaviors. One striking feature is a failure to return to equilibrium af…
Symmetry Breaking and Energy Dissipation in the Mechanical Response of Amorphous Solids
Itamar Procaccia, Tuhin Samanta
Dissipation, or the loss of energy conservation, is necessarily related to symmetry breaking. Here we study the symmetry breaking that is responsible for dissipation in the mechani…
