ABSTRACT
Dense granular materials and glass forming systems share many properties (Nagel, 2000), such as slow relaxation, aging and rejuvenation, when driven towards the jamming, respectively the glass transition. Such similar behaviours at the macroscopic level call for a common description of both systems. More specifically, given their fundamental difference (granular matter being athermal), one would like to know what are the microscopic mechanisms at the root of these generic properties.
