卷吸和单位速度：加速排斥过程中的意外
Entrainment and unit velocity: Surprises in an accelerated exclusion process
摘要：
我们介绍了一类距离依赖的相互作用，在加速排斥过程（AEP）的灵感来自于观察转录RNA聚合酶加速时，“推”一个尾随的。在环上，AEP稳态显示出从均匀（具有增强电流）到相分离的不连续过渡。在后一种状态下，这些孔看起来松散地结合在一起并一起移动，很像一列训练。令人惊讶的是，电流-密度关系仅仅是$J=1-ρ$，这意味着“空穴串”以\textit{unit}速度运动。
英文摘要：
We introduce a class of distance-dependent interactions in an accelerated exclusion process (AEP) inspired by the observation of transcribing RNA polymerase speeding up when "pushed" by a trailing one. On a ring, the AEP steady state displays a discontinuous transition, from being homogeneous (with augmented currents) to phase-segregated. In the latter state, the holes appear loosely bound and move together, much like a train. Surprisingly, the current-density relation is simply $J=1-ρ$, signifying that the "hole-train" travels with \textit{unit} velocity.
