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 Holography: Towards a Unification of Landau and Beyond-Landau Physics
Heidar Moradi, Seyed Faroogh Moosavian, Apoorv Tiwari
We outline a holographic framework that attempts to unify Landau and beyond-Landau paradigms of quantum phases and phase transitions. Leveraging a modern understanding of symmetrie…

Symmetry fractionalization, mixed-anomalies and dualities in quantum spin models with generalized symmetries
Heidar Moradi, Ãmer M. Aksoy, Jens H. Bardarson +1
We investigate the gauging of higher-form finite Abelian symmetries and their sub-groups in quantum spin models in spatial dimensions and 3. Doing so, we naturally uncover ga…
