Fig. 7: β-function and conductance fitting near the ballistic limit.
From: Anderson critical metal phase in trivial states protected by average magnetic crystalline symmetry
a The β-function of the network model derived from finite differences of conductance data in Fig. 1f. The legends inform the central sizes of the finite differences. The insect is the zoom out of the β-function for large G. b Conductance fitting according to the linear hypothesis of β-function for large G. Colored curves are fitting results while the circles are raw data. The goodness of fit has reached 0.23 and will become higher as getting closer to the ballistic limit. (1 corresponds to a perfect fitting and 0.05 is the frequently used threshold of accepting a fitting hypothesis).
