Figure 1

Averaged correlation function $C^{xx}(L/2)$ as a function of the system size $L$ in a log-log plot for $W=0$, 0.25, 0.5, 0.75, and 1.0 (top to bottom). The data are averaged over 50 000 for $L\le 1024$, 3000 for $L=2048$, and 500 for $L=4096$; the statistical error is smaller than the symbol sizes. The data for the pure system ($W=0$) follow $C^{xx}(L/2)\propto L^{-1/2}$; the full line with slope $-2$ is the expected asymptotic behavior according to the IRFP scenario [2]. Inset: Scaling plot according to Eq. (3) for the data of the main figure with ${\xi }_W=600$, 140, 54, and 20 for $W=0.25$, 0.5, 0.75, and 1.0, respectively.Reuse & Permissions
