From: Fragile topological band in the checkerboard antiferromagnetic monolayer FeSe

Fig. 4

a, b Spin-polarized edge states along the cuts #2 and #3 boundary, respectively. The weights of positive (negative) σz eigenvalue is characterized as red (blue). The inset pictures show the calculated mass term σy near the massive Dirac cone. c Energy spectra of the 20 × 20 finite square structure. d Spatial distribution of the two occupied corner states.
