摘要:

研究了二维晶格网络在广义Achlioptas过程(GAP)下的逾渗相变。在GAP过程中,从晶格中随机选择两个边,并将具有两个连接簇大小的最小乘积的边作为下一个被占用的键,其概率为$p$。在$p=0.5$,GAP变成随机增长模型,并导致在$p=1$的少数产品规则。通过有限尺寸标度分析,我们发现这些含$0.5 \le p \le 1$体系的渗流相变总是连续的,临界指数依赖于$p$ .因此,二维格点网络中的临界现象的普适类还与概率参数$p$有关。

英文摘要:

The percolation phase transitions of two-dimensional lattice networks under a generalized Achlioptas process (GAP) are investigated. During the GAP, two edges are chosen randomly from the lattice and the edge with minimum product of the two connecting cluster sizes is taken as the next occupied bond with a probability $p$. At $p=0.5$, the GAP becomes the random growth model and leads to the minority product rule at $p=1$. Using the finite-size scaling analysis, we find that the percolation phase transitions of these systems with $0.5 \le p \le 1$ are always continuous and their critical exponents depend on $p$. Therefore, the universality class of the critical phenomena in two-dimensional lattice networks under the GAP is related to the probability parameter $p$ in addition.
