Data for: Dual topology and edge-reconstruction in α-Sn

This dataset contains the numerical data underlying Figures 11, 12, 13, 15 and 16 of the article “Dual topology and edge-reconstruction in α-Sn”, Phys. Rev. B (2026). The data were obtained from tight-binding calculations for α-Sn. Each figure is provided as a separate zip archive containing the data files and a README with the figure caption and a description of the data format. For Figures 15 and 16, the archives also include the Python scripts that reproduce the figures. Figures 11–13 were produced in Mathematica, and their plotting code is not included. Contents: fig11_hinge_states.zip: band structure of a system finite in x and y and periodic along z, and the local charge density of the hinge-state manifold fig12_edge_spectrum.zip: edge-state band structures versus k₁ at k₂ = 0 and k₂ = π for a slab of N₃ = 100 layers fig13_wilson_loop_phases.zip: phases of the Wilson-loop eigenvalues along k₃ versus k₁ at k₂ = π fig15_surface_potential.zip: effect of a surface potential on the edge-state spectrum fig16_inv_map_strain_t.zip: phase diagrams in the (θ/θ₀, t) plane for slab thicknesses N₃ = 10, 20, 40
