Third-order topological insulators with wallpaper fermions in Tl4PbTe3 and Tl4SnTe3
Abstract Nonsymmorphic symmetries open up horizons of exotic topological boundary states and even generalize the bulk–boundary correspondence, which, however, the third-order topological insulator in electronic materials are still unknown. Here, by means of the symmetry analysis and k · p models, we...
