A recent granular rheology based on an implicit “granular fluidity” field has been shown to
quantitatively predict many nonlocal phenomena. However, the physical nature of the field …

Dense particle packing in a confining volume remains a rich, largely unexplored problem,
despite applications in blood clotting, plasmonics, industrial packaging and transport …

Size segregation, which is a robust feature of sheared granular mixtures and geophysical
mass flow deposits, is found to diminish in the presence of a viscous fluid. We study this …

The kinematics and the shear-induced alignment of elongated particles in confined,
heterogeneous flow conditions are investigated experimentally. Experiments are conducted …

We demonstrate an efficient cross-phase modulation (XPM) based on a closed-loop double-
Λ system. The property of the double-Λ medium can be controlled by changing the phases of …

Numerous large‐scale geophysical flows propagate with low‐apparent basal friction
coefficients, but the source of such phenomenology is poorly known. Motivated by scarce …

Hydrodynamic approaches that treat granular materials as a continuum via the
homogenization of discrete flow properties have become viable options for efficient …

Base roughness plays an important role in the dynamics of granular flows but is still poorly
understood due to the difficulty of its quantification. For a bumpy base made of spheres, at …

Geophysical flows grow in volume and impact potential by eroding and entraining bed
material during movement, posing potential risks to human lives and facilities downstream …

We study the rheology of dense granular flows for frictionless spherocylinders by means of
3D numerical simulations. As in the case of spherical particles, the effective friction μ is an …
