TASEP速度过程的标度极限

Scaling limit of the TASEP speed process

Ofer Busani, Timo Seppäläinen, Evan Sorensen

AI总结:

本文证明TASEP速度过程在速度零附近标度到平稳地平线(SH),从而建立多型平稳分布的非平凡标度极限,为SH作为KPZ普适类中Busemann过程普适标度极限提供了新证据。

摘要:

我们证明,完全非对称简单排他过程(TASEP)的多型平稳分布在密度为 $1/2$ 的伯努利测度附近标度到一个非平凡的极限。这一结果是通过证明 TASEP 速度过程——由 Amir、Angel 和 Valkó 引入——在速度 $v=0$ 附近标度到平稳地平线(SH)而得到的。SH 是作者最近引入并研究的函数值随机过程,据信它是 KPZ 普适类中 Busemann 过程的普适标度极限。我们的结果通过将 SH 与多类粒子构型联系起来,为这一普适性增添了证据。此前 SH 已与指数角增长模型、布朗末通过渗流以及有向景观相关联。

英文摘要:

We show that the multi-type stationary distribution of the totally asymmetric simple exclusion process (TASEP) scales to a nontrivial limit around the Bernoulli measure of density $1/2$. This is obtained by showing that the TASEP speed process, introduced by Amir, Angel and Valkó, scales around the speed $v=0$ to the stationary horizon (SH), a function-valued stochastic process recently introduced and studied by the authors, SH is believed to be the universal scaling limit of Busemann processes in the KPZ universality class. Our results add to the evidence for this universality by connecting SH with multiclass particle configurations. Previously SH has been associated with the exponential corner growth model, Brownian last-passage percolation, and the directed landscape.
