摘要翻译：
通过比较Edwards-Anderson自旋玻璃模型在周期和反周期边界条件下的基态，我们直接研究了畴壁的长度。对于双峰和高斯键分布，我们分离了DW，并直接计算了它的分形维数D_f$。我们的结果表明，即使在三维中，两种键的分布的D_F$是相同的，但在二维(2D)体系中显然不是这样。此外，与键为高斯分布的2D Edwards-Anderson自旋玻璃的情况相反，我们没有发现键为双峰分布的DW可以描述为Schramm-Loewner演化过程。

英文摘要：
We study directly the length of the domain walls (DW) obtained by comparing the ground states of the Edwards-Anderson spin glass model subject to periodic and antiperiodic boundary conditions. For the bimodal and Gaussian bond distributions, we have isolated the DW and have calculated directly its fractal dimension $d_f$. Our results show that, even though in three dimensions $d_f$ is the same for both distributions of bonds, this is clearly not the case for two-dimensional (2D) systems. In addition, contrary to what happens in the case of the 2D Edwards-Anderson spin glass with Gaussian distribution of bonds, we find no evidence that the DW for the bimodal distribution of bonds can be described as a Schramm-Loewner evolution processes.
