From: Field-induced multiple metal-insulator crossovers of correlated Dirac electrons of perovskite CaIrO3

a Calculated energy dispersion near the line node. The band crossing due to the line node is denoted by blue circles. Here the origin is U-point in the momentum space [See Supplementary Fig. 9]. b, c, and d Landau levels around the U-point under the magnetic field of 10, 20, and 50 T, respectively. The magnetic field is applied along a-axis of the crystal (B||a(z)). e Density of states at B = 0.1, 10, 20, and 50 T. f The density of states at 0 eV as a function of the magnetic field. g The magnetic field dependence of ΔEF. The definition of ΔEF is shown in a, b, c, and d.
