(a) Faber–Ziman total structure factor \(S_{\textrm FZ}(Q)\) for ND and XRD computed via MLMD simulation. The black, blue, and red lines represent the structure factors for OSG, SGUP, and DSG, respectively. The values in \((\cdot )\) in the legends denote the density of silica glass [g/cm\(^{3}\)]. (b) shows the density dependence of position (upper panel) and height (lower panel) of the FSDP in the Faber–Ziman structure factor of ND. The black dots denote the results of the SGUP. The blue, green, purple, and red dots represent the results of the DSGs compressed at 2000, 2500, 3000, and 3500 K (DSG2000, DSG2500, DSG3000, and DSG3500), respectively. The orange squares denote the experimental data of the DSG27.
