Elastoplasticity mediates dynamical heterogeneity below the mode coupling temperature

RN Chacko, FP Landes, G Biroli, O Dauchot, AJ Liu… - Physical Review Letters, 2021 - APS
As liquids approach the glass transition temperature, dynamical heterogeneity emerges as a
crucial universal feature of their behavior. Dynamic facilitation, where local motion triggers …

Mean-field theory of yielding under oscillatory shear

JT Parley, S Sastry, P Sollich - Physical Review Letters, 2022 - APS

local yield barriers, to shed light on the behavior of athermal amorphous solids subject to …

Scaling description of creep flow in amorphous solids

M Popović, TWJ de Geus, W Ji, A Rosso, M Wyart - Physical Review Letters, 2022 - APS
Amorphous solids such as coffee foam, toothpaste, or mayonnaise display a transient creep
flow when a stress Σ is suddenly imposed. The associated strain rate is commonly found to …

Metastability as a mechanism for yielding in amorphous solids under cyclic shear

M Mungan, S Sastry - Physical review letters, 2021 - APS
We consider the yielding behavior of amorphous solids under cyclic shear deformation and
show that it can be mapped into a random walk in a confining potential with an absorbing …

Unified view of avalanche criticality in sheared glasses

N Oyama, H Mizuno, A Ikeda - Physical Review E, 2021 - APS
Plastic events in sheared glasses are considered an example of so-called avalanches,
