类Kagome晶格临界逾渗阈值的普适条件

Universal condition for critical percolation thresholds of kagome-like lattices

Robert M. Ziff, Hang Gu

摘要:

格,可以表示在一个kagome的形式,以满足一个普遍的渗流临界条件,表示为P_3之间的关系,所有的三个顶点连接的概率,和P_0,没有连接的概率。导出了P_3(P_0)的线性近似,并给出了临界阈值的严格上界。数值确定的P_3(P_0)关系给出了可果美、点键蜂窝、(3- 12 ^2)和“三角形堆叠”晶格的阈值,这些阈值与数值结果相比是有利的。

英文摘要:

Lattices that can be represented in a kagome-like form are shown to satisfy a universal percolation criticality condition, expressed as a relation between P_3, the probability that all three vertices in the triangle connect, and P_0, the probability that none connect. A linear approximation for P_3(P_0) is derived and appears to provide a rigorous upper bound for critical thresholds. A numerically determined relation for P_3(P_0) gives thresholds for the kagome, site-bond honeycomb, (3-12^2), and "stack-of-triangle" lattices that compare favorably with numerical results.
