Extended Data Fig. 7: Fitting to the differential conductance data based on the universal scaling formula.
From: One-dimensional Luttinger liquids in a two-dimensional moiré lattice
a, Raw data for the differential conductance measurements taken in device no. 1 (replotted from Fig. 2d). b, 2D map of calculated root-mean-square error (r.m.s.e.) as a function of the fitting parameters, α and γ (see Methods for details). The best fit is obtained by finding the minimal value of r.m.s.e. in this plot, i.e., α = 0.94 and 1/γ = 9. c & d, Scaled conductance as a function of scaled excitation by assigning α = 0.94 in a log–log plot and log-linear plot. The dashed line indicates the fitting result given by the universal formula defined in the Method section. e-h, The same fitting plots for device no. 2, using the same raw data shown in Fig. 2f.
