人们能为致密的、缓慢运动的粉末和颗粒建立热力学吗？几年前，爱德华兹提出了一个可能的方向，提出了一个迷人的观点，即这样的系统有自己的统计力学，不同于麦克斯韦，玻尔兹曼和吉布斯，使我们有一些信息，而仍然忽略动态细节。玻璃理论的最新发展在平均场范围内证实了这些想法。为了超越，我们显式生成爱德华兹的措施在一个三维模型。与不可逆压缩数据的比较表明，结果非常好的协议。目前的框架立即提出了新的实验检查。
Can one construct a thermodynamics for compact, slowly moving powders and grains? A few years ago, Edwards proposed a possible step in this direction, raising the fascinating perspective that such systems have a statistical mechanics of their own, different from that of Maxwell, Boltzmann, and Gibbs, allowing us to have some information while still ignoring dynamic details. Recent developments in the theory of glasses have come to confirm these ideas within mean field. In order to go beyond, we explicitly generate Edwards' measure in a 3D model. Comparison of the results with the irreversible compaction data shows very good agreement. The present framework immediately suggests new experimental checks.
