Granular Matter 3, 5761 c Springer-Verlag 2001 Glassy models for granular systems

Summary: Granular Matter 3, 57­61 c Springer-Verlag 2001
Glassy models for granular systems
Jeferson J. Arenzon, Mauro Sellitto
Abstract We briefly review some simple lattice models,
introduced recently to study granular systems based on
the similarities with glassy systems. The basic common
ingredient, partially responsible for the complex behavior
shown, is geometric frustration due to steric hindrance.
Keywords Granular matter, glassyness, lattice models
For many agricultural and industrial processes, proper
handling of granular material pose several fundamental
practical problems that only recently have attracted the
attention of physicists [1­3]. Because of its unusual stat-
ic and flowing properties, the subject offers a challenging
problem from the theoretical point of view, and despite
the huge effort devoted to them, are far from being fully
understood. Therefore, since even the basic mechanisms
responsible for the very unintuitive properties presented
