Lieb-Schultz-Mattis anomalies and web of dualities induced by gauging in quantum spin chains
Ömer M. Aksoy, Christopher Mudry, Akira Furusaki +1
Lieb-Schultz-Mattis (LSM) theorems impose non-perturbative constraints on the zero-temperature phase diagrams of quantum lattice Hamiltonians (always assumed to be local in this pa…
Symmetry fractionalization, mixed-anomalies and dualities in quantum spin models with generalized symmetries
Heidar Moradi, Ömer 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…
Single monkey-saddle singularity of a Fermi surface and its instabilities
Ömer M. Aksoy, Anirudh Chandrasekaran, Apoorv Tiwari +3
Fermi surfaces can undergo sharp transitions under smooth changes of parameters. Such transitions can have a topological character, as is the case when a higher-order singularity,…
