圆上的简单排它过程具有扩散截止窗口

The Simple Exclusion Process on the Circle has a diffusive Cutoff Window

Hubert Lacoin

摘要:

本文研究了具有$N$格点的圆上简单排它过程的混合时间,其中粒子数$k(N)$趋于无穷大,无论是从最坏的初始条件还是从典型的初始条件.我们发现,最坏情况下的混合时间是渐近等价于$(8π^2)^{-1}N^2\log k$,而截止窗口,被确定为$N^2$。从一个典型的条件,我们表明,有没有截止和混合时间的顺序为$N^2$。

英文摘要:

In this paper, we investigate the mixing time of the simple exclusion process on the circle with $N$ sites, with a number of particle $k(N)$ tending to infinity, both from the worst initial condition and from a typical initial condition. We show that the worst-case mixing time is asymptotically equivalent to $(8π^2)^{-1}N^2\log k$, while the cutoff window, is identified to be $N^2$. Starting from a typical condition, we show that there is no cutoff and that the mixing time is of order $N^2$.
