TASEP中的普适退出概率

Universal exit probabilities in the TASEP

S. S. Poghosyan, A. M. Povolotsky, V. B. Priezzhev

摘要:

研究了完全非对称简单排斥过程(TASEP)中粒子从给定形式的时空集合中的联合退出概率。我们扩展了以前的结果上的时空关联函数的TASEP,这对应于出口的垂直或水平直线所界定的集合。特别是,我们的方法使我们能够删除以前的研究中使用的时间矩的排序,以便只保留粒子坐标的自然空间排序。我们考虑序列一般阶梯状的边界从东北到西南的时空平面。从给定的集合的退出概率导出的形式Fredholm行列式定义的边界上的集合。在尺度极限下,阶梯状边界被视为连续可微曲线的近似。对于这些曲线上属于任意类空路径的点,其退出概率收敛于普适的Airy $_2$过程.

英文摘要:

We study the joint exit probabilities of particles in the totally asymmetric simple exclusion process (TASEP) from space-time sets of given form. We extend previous results on the space-time correlation functions of the TASEP, which correspond to exits from the sets bounded by straight vertical or horizontal lines. In particular, our approach allows us to remove ordering of time moments used in previous studies so that only a natural space-like ordering of particle coordinates remains. We consider sequences of general staircase-like boundaries going from the northeast to southwest in the space-time plane. The exit probabilities from the given sets are derived in the form of Fredholm determinant defined on the boundaries of the sets. In the scaling limit, the staircase-like boundaries are treated as approximations of continuous differentiable curves. The exit probabilities with respect to points of these curves belonging to arbitrary space-like path are shown to converge to the universal Airy$_2$ process.
