Topological characterization of multifold band degeneracies in Altland-Zirnbauer symmetry classes
Askar Iliasov, Zoltán Guba, Tsuneya Yoshida +2
Topological degeneracies of energy bands in crystalline matter are conventionally characterized by invariants computed on an enclosing sphere over which the spectrum remains gapped…

Topological non-Abelian gauge structures in Cayley-Schreier lattices
Zoltán Guba, Robert-Jan Slager, Lavi K. Upreti +1
Crystalline constructions known as Cayley-Schreier lattices have been suggested as a platform for realizing arbitrary gauge fields in synthetic crystals with real hopping amplitude…

Delicate Wannier insulators
Zoltán Guba, Aris Alexandradinata, Tomáš Bzdušek
The defining feature of topological insulators is that their valence states are not continuously deformable to a suitably defined atomic limit without breaking the symmetry or clos…
