Lastly, it was subsequently shown in ref. 58 that fourfold Dirac fermion doubling can also be evaded in lattice models of 2D magnetic SMs with the symmetry {T|a/2} common to Type-IV 2D symmetry (wallpaper or layer) groups (see SN 15). Hence, one may infer the existence of novel ...

(7) to all wallpaper groups in Supplementary Note 3, obtaining topological invariants of many-body fragile phases. In Supplementary Table 5, we give expressions for the local RSIs on product states in terms of irrep multiplicities and also single-particle RSIs which are readily computed from ...
. This reflects the characteristic common features of all classes of compounds, determined by the position of anion forming elements in the Periodic table of the elements. The second order (sublevel) represents the subdivision of classes and is usually also based on the composition of compounds or...
