临界渗流中最短路径的序贯破坏

Sequential disruption of the shortest path in critical percolation

Oliver Gschwend, Hans J. Herrmann

摘要:

通过比较渗流团簇的最短路径与最短替代路径,研究了临界状态下连续破坏渗流团簇的最短路径的效果,测量了两条路径的长度和封闭面积的差异。序贯方法允许研究空间相关性。我们发现长度连续恒定差异的线段的长度是不相关的。同时,我们研究了红键之间的距离。我们发现封闭区域A的概率分布,长度$Δl$的差异,以及红键$l_r$之间的长度遵循幂律分布。用极大似然估计和外推法,我们发现$Δl$的指数$β$ = 1.38 $\pm$ 0.03,A的指数$α$ = 1.186 $\pm$ 0.008,$l_r$的指数$δ$ = 1.64 $\pm$ 0.025。

英文摘要:

We investigate the effect of sequentiallydisrupting the shortest path of percolation clusters at criticality by comparing it with the shortest alternative path. We measure the difference in length and the enclosed area between the two paths. The sequential approach allows to study spatial correlations. We find the lengths of the segments of successively constant differences in length to be uncorrelated. Simultaneously, we study the distance between red bonds. We find the probability distributions for the enclosed areas A, the differences in length $Δl$, and the lengths between the redbonds $l_r$ to follow power law distributions. Using maximum likelihood estimation and extrapolation we find the exponents $β$ = 1.38 $\pm$ 0.03 for $Δl$, $α$ = 1.186 $\pm$ 0.008 for A and $δ$ = 1.64 $\pm$ 0.025 for thedistribution of $l_r$.
