Topological characterization of multifold band degeneracies in Altland-Zirnbauer symmetry classes
Askar Iliasov, Zoltán Guba, Tsuneya Yoshida +2
The paper develops a topological classification for generic n‑fold band degeneracies that are protected solely by Altland‑Zirnbauer symmetries, using linked nodal manifolds instead…

Topological non-Abelian Gauge Structures in Cayley-Schreier Lattices
Zoltán Guba, Robert-Jan Slager, Lavi K. Upreti +1
Recently, novel crystalline constructions known as Cayley-Schreier lattices have been suggested as a platform for realizing arbitrary gauge fields in synthetic crystals with real h…

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…
