Dense colloidal suspensions and related glass-forming fluids show pronounced nonlinear
(non-Newtonian) flow effects, since slow internal relaxation competes with the imposed …

In the absence of periodicity, the structure of glass is ill-defined, and a large number of
structural states are found at similar energy levels. However, little is known about how these …

Absorbing phase transitions (APTs) are widespread in nonequilibrium systems, spanning
condensed matter, epidemics, earthquakes, ecology, and chemical reactions. APTs feature …

Using molecular dynamics simulations, we study the transient response of a binary Lennard-
Jones glass subjected to periodic shear deformation. The amorphous solid is modeled as a …

Repeated/cyclic shearing can drive amorphous solids to a steady state encoding a memory
of the applied strain amplitude. However, recent experiments find that the effect of such …

We examine a two-dimensional system of sterically repulsive interacting disks where each
particle runs in a random direction. This system is equivalent to a run-and-tumble dynamics …

Molecular dynamics simulations are performed to examine the dynamic response of
amorphous solids to oscillatory shear at finite temperatures. The data were collected from a …

We report x-ray photon correlation spectroscopy experiments on a concentrated
nanocolloidal gel subject to in situ oscillatory shear strain. The strain causes periodic …

Athermal disordered systems can exhibit a remarkable response to an applied oscillatory
shear: After a relatively few shearing cycles, the system falls into a configuration that had …

The behavior of shear-oscillated amorphous materials is studied using a coarse-grained
model. Samples are prepared at different degrees of annealing and then subjected to …
