摘要：
We show that the inherent states of glassy systems and granular materials can be described in the framework of standard Statistical Mechanics as originally proposed by Edwards. We introduce a "tapping" dynamics in the space of the inherent states based on the dynamics used in granular matter. It is assumed that under stationarity or quasi-stationarity the distribution among the inherent states satisfies the principle of maximum entropy. This leads to a distribution characterised by a configurational temperature related to Edwaxds compactivity. Finally the prediction are checked on a lattice model.
