Elastoplasticity mediates dynamical heterogeneity below the mode coupling temperature
As liquids approach the glass transition temperature, dynamical heterogeneity emerges as a
crucial universal feature of their behavior. Dynamic facilitation, where local motion triggers …

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