Solids deform and fluids flow, but soft glassy materials, such as emulsions, foams,
suspensions, and pastes, exhibit an intricate mix of solid-and liquid-like behavior. While …

When weakly jammed packings of soft, viscous, non-Brownian spheres are probed
mechanically, they respond with a complex admixture of elastic and viscous effects. While …

We numerically investigate stress relaxation in soft athermal disks to reveal critical slowing
down when the system approaches the jamming point. The exponents describing the …

We investigate irreversibility in soft frictionless disk packings on approach to the unjamming
transition. Using simulations of shear reversal tests, we study the relationship between …

Aqueous foams are an important model system that displays coarsening dynamics.
Coarsening in dispersions and foams is well understood in the dilute and dry limits, where …

We report x-ray photon correlation spectroscopy (XPCS) experiments with in situ rheometry
performed on a soft glass composed of a concentrated suspension of charged silica …

Networks and dense suspensions frequently reside near a boundary between soft (or
fluidlike) and rigid (or solidlike) regimes. Transitions between these regimes can be driven …

Linear response theory relates the response of a system to a weak external force with its
dynamics in equilibrium, subjected to fluctuations. Here, this framework is applied to …
