平面$Φ^{3}$随机图上的点渗流

Site Percolation on Planar $Φ^{3}$ Random Graphs

J. -P. Kownacki

摘要:

本文用Monte-Carlo数值方法研究了随机$Φ^{3}$平面图上的位点渗流问题。该方法包括从由蒙特卡罗模拟生成的图中随机移除顶点的一部分$q=1-p$,其中$p$是占用概率。由此产生的图是由被占用的站点的集群组成的。通过测量它们分布的几个性质,表明对于高于渗流阈值$p_{c}$ =0.7360(5)的占用概率,发生渗流。此外,临界指数是兼容的那些解析已知的债券渗流。

英文摘要:

In this paper, site percolation on random $Φ^{3}$ planar graphs is studied by Monte-Carlo numerical techniques. The method consists in randomly removing a fraction $q=1-p$ of vertices from graphs generated by Monte-Carlo simulations, where $p$ is the occupation probability. The resulting graphs are made of clusters of occupied sites. By measuring several properties of their distribution, it is shown that percolation occurs for an occupation probability above a percolation threshold $p_{c}$=0.7360(5). Moreover, critical exponents are compatible with those analytically known for bond percolation.
