论文摘要
在振荡性剪切的影响下,摩擦颗粒圆盘的单层显示了两个动力学相变:从最初无序状态到有序的结晶状态的过渡,以及动态的活性吸收相变。尽管没有理由,但{\ it a-priori},它们是在同一关键点上。过渡也可以以磁盘轨迹为特征,磁盘轨迹是非平凡的环路破坏了时间转换的不变性。
Under the influence of oscillatory shear, a mono-layer of frictional granular disks exhibits two dynamical phase transitions: a transition from an initially disordered state to an ordered crystalline state, and a dynamic active-absorbing phase transition. Although there is no reason, {\it a-priori}, for these to be at the same critical point, they are. The transitions may also be characterized by the disk trajectories, which are non-trivial loops breaking time-reversal invariance.
