When a system jams, it undergoes a transition from a flowing to a rigid state. Despite this
important change in the dynamics, the internal structure of the system remains disordered in …

At the core of equilibrium statistical mechanics lies the notion of statistical ensembles: a
collection of microstates, each occurring with a given a priori probability that depends on …

A non-local theory is proposed to model dense granular flows. The idea is to describe the
rearrangements occurring when a granular material is sheared as a self-activated process …

The discrete element modelling of triaxial tests plays a critical role in unveiling fundamental
properties of particulate materials, but the numerical implementation of a flexible membrane …

We study how a shear band in a granular medium dramatically changes the mechanical
behavior of the material further in the non sheared region. To this end, we carry out a …

We study the rheology of amorphous packings of soft, frictionless particles close to jamming.
Implementing a quasistatic simulation method we generate a well-defined ensemble of …

We establish that the rheological curve of dry granular media is nonmonotonic, both in the
presence and absence of external mechanical agitations. In the presence of weak …

We describe experiments that probe the evolution of shear jammed states, occurring for
packing fractions ϕ S≤ ϕ≤ ϕ J, for frictional granular disks, where above ϕ J there are no …

The physical properties of granular materials have been extensively studied in recent years.
So far, however, there exists no theoretical framework which can explain the observations in …

We use numerical simulations to study the dynamics of dense assemblies of self-propelled
particles in the limit of extremely large, but finite, persistence times. In this limit, the system …
