We compare the predictions of two different statistical mechanics approaches, corresponding to different physical measurements, proposed to describe binary granular mixtures subjected to some external driving (continuous shaking or tap dynamics). In particular we analytically solve at a mean field level the partition function of a simple hard sphere lattice model under gravity and focus on the phenomenon of size segregation. We find that the two approaches lead to similar results and seem to…

Shear-induced segregation of a granular mixture under horizontal oscillation

We study the segregation process of a granular mixture of discs on an horizontally oscillating tray by realistic molecular dynamics simulations. As found in the experiments, we observe the initially

Species Segregation and Dynamical Instability of Horizontally Vibrated Granular Mixtures

We review recent results about the segregation process of a granular mixture of disks on an horizontally oscillating tray. In this condition an initially disordered mixture first segregates via the

Jamming transition in granular media: a mean-field approximation and numerical simulations.

These results confirm early speculations about the connection between the jamming transition in granular media and the glass transition in usual glass formers, giving moreover a precise interpretation of its nature.

Jamming in Dense Granular Media

We review some recent results on Statistical Mechanics approach to dense granular media. In particular, by analytical mean field investigation we derive the phase diagram of a monodisperse system. We

Granular segregation in dense systems: the role of statistical mechanics and entropy

Granular segregation is ubiquitous in industrial, geological or daily-life context, but there is still no unifying theoretical approach. In this review, we examine two examples of granular

Convection, Segregation and Pattern Formation in Horizontally Vibrated Granular Materials

We reviewed the developments in segregation, convection and pattern formation in horizontally vibrated granular systems which are important for the improvement of several industrial developments,

Spiral trajectory in the horizontal Brazil nut effect.

An intruder to a group of identical beads contained in a circular plate which is subjected to a circular vibration will trace approximately a cyclic spiral. The trajectory is a result of both

Statistical mechanics of dense granular media

We discuss some recent results on the statistical mechanics approach to dense granular media. In particular, by analytical mean field investigation we derive the phase diagram of monodisperse and
