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 show that '' jamming '' corresponds to a phase transition from a '' fluid '' to a '' glassy '' phase. The nature of such a '' glassy '' phase turns out to be the same found in mean field models for glass formers. This gives quantitative evidence to the idea of a unified description of the '' jamming '' transition in granular media and thermal systems, such as glasses.

Abstract
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 show that '' jamming '' corresponds to a phase transition from a '' fluid '' to a '' glassy '' phase. The nature of such a '' glassy '' phase turns out to be the same found in mean field models for glass formers. This gives quantitative evidence to the idea of a unified description of the '' jamming '' transition in granular media and thermal systems, such as glasses.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
