Abstract: Abstract The discrete element method has been widely adopted to study the phononic dispersion relation of granular crystals, but its intrinsic limitations in the conventional particle contact model are often overlooked. In this study, we… read more here.

Abstract: Transient creep mechanisms in soft granular packings are studied numerically using a constant pressure and constant stress simulation method. Rapid compression followed by slow dilation is predicted on the basis of a logarithmic creep phenomenon.… read more here.

Abstract: We study the dynamics of threads of monodisperse droplets, including droplet chains and multi-chains, in which the droplets are interconnected by capillary bridges of another immiscible liquid phase. This system represents wet soft-granular matter –… read more here.

DOI: 10.1103/physrevlett.128.128001
Abstract: We report new dynamical modes in confined soft granular flows, such as stochastic jetting and dripping, with no counterpart in continuum viscous fluids. The new modes emerge as a result of the propagation of the… read more here.
