递归逾渗

Recursive Percolation

Youjin Deng, Jesper Lykke Jacobsen, Xuan-Wen Liu

摘要:

我们介绍了一个简单的晶格模型,在该模型中,渗流构造在临界渗流集群的顶部,并表明它可以递归地重复任何数量的$n$代。在两个维度上,我们确定了高达$n=5$的逾渗阈值。随着$n$的增加,相应的临界簇变得越来越紧凑,并且定义了标准二维形式的通用标度函数和对于任何$n$都不同的临界指数。这个指数族不同于任何以前已知的普适类,并且不能被现有的分析方法所容纳。我们确认,递归渗流是定义良好的三维空间。

英文摘要:

We introduce a simple lattice model in which percolation is constructed on top of critical percolation clusters, and show that it can be repeated recursively any number $n$ of generations. In two dimensions, we determine the percolation thresholds up to $n=5$. The corresponding critical clusters become more and more compact as $n$ increases, and define universal scaling functions of the standard two-dimensional form and critical exponents that are distinct for any $n$. This family of exponents differs from any previously known universality class, and cannot be accommodated by existing analytical methods. We confirm that recursive percolation is well defined also in three dimensions.
