标题： Rigid cluster decomposition reveals criticality in frictional jamming

摘要： 我们研究了摩擦阻塞转变的性质，这是在刚度渗流理论的框架下进行的。 缓慢剪切的摩擦性堆积被分解为刚性簇和柔性区域，这是对包含摩擦接触的 Pebble 游戏的一种推广。 我们发现了一个二级相变，其由一个贯穿整个系统的刚性簇的出现所控制，并伴随着临界簇大小分布。 刚性簇也与常见的刚度度量相关。 我们将这一结果与无摩擦阻塞进行对比，其中刚性簇大小分布是非临界的。 显示英文摘要

摘要： We study the nature of the frictional jamming transition within the framework of rigidity percolation theory. Slowly sheared frictional packings are decomposed into rigid clusters and floppy regions with a generalization of the pebble game including frictional contacts. We discover a second-order transition controlled by the emergence of a system-spanning rigid cluster accompanied by a critical cluster size distribution. Rigid clusters also correlate with common measures of rigidity. We contrast this result with frictionless jamming, where the rigid cluster size distribution is noncritical.
