a Total density of states ρ(ε) in logarithmic scale as a function of energy ε and pseudomagnetic flux ατ. The size of the sample is the same as in Fig. 3, namely Lx = 450.5 a. The black dashed and dashed-dotted lines represent the chemical potentials μ1 = 0.02t and μ2 = 0.068t, respectively. b Cut of (a) for ατ = 3.255 × 10−4 (identified with vertical dashed-blue line in (a). c Bulk density of states ρbulk(ε) in logarithmic scale for Lbulk = 36 a. d Cut of (c) for ατ = 3.255 × 10−4. In (b) and (d), black solid lines identify the energy of the analytical pseudo-Landau levels at the Dirac points.
