自洽的关联渗流问题

本文用实空间重整化群方法处理有粹灭关联的渗流系统。我们选择最近邻短程序α为关联参量。对于关联的几率我们做了自洽的处理。在二维我们的结果表明只有一个非平庸的物理不动点,关联在无序渗流点附近是个无用参量,这与其他的关联渗流模型一致。 关键词：

SELF-CONSISTENT CORRELATED PERCOLATION

The critical properties of a quenched site-correlated percolation system is treated by real-space renormalization group method. We chose the nearest-neighbour short-range order a as the correlation parameter. By treating the correlated probability self-consistently, we found, in two dimension, there is only one nontrivial physical fixed point and the correlation is an irrelevant parameter at random percolation fixed point, which is consistent with other correlated percolation models.
