巨星系团切片中$3d$渗流的高精度异常维数

High-precision anomalous dimension of $3d$ percolation from giant cluster slicing

Alessandro Galvani, Andrea Trombettoni, Giacomo Gori

摘要:

我们将临界几何方法应用于有界临界现象[1]到$3d$渗流。序参量分布$ϕ$的函数形状通过分数Yamabe方程与其标度维数$Δ_ϕ$相关。我们得到$Δ_ϕ= 0.4785(7)$,从该异常尺寸$η$被发现是$η=-0.0431(14)$,一个值兼容,更精确的比,它以前的直接测量。并进行了超尺度检验。

英文摘要:

We apply the critical geometry approach for bounded critical phenomena [1] to $3d$ percolation. The functional shape of the order parameter profile $ϕ$ is related via the fractional Yamabe equation to its scaling dimension $Δ_ϕ$. We obtain $Δ_ϕ= 0.4785(7)$ from which the anomalous dimension $η$ is found to be $η=-0.0431(14)$, a value compatible with, and more precise than, its previous direct measurements. A test of hyperscaling is also performed.
