Emanant and emergent symmetry-topological-order from low-energy spectrum
Zixin Jessie Chen, Ãmer M. Aksoy, Cenke Xu +1
Low-energy emanant and emergent symmetries can be anomalous, higher-group, or non-invertible. A way to systematically capture the properties of such symmetries is through the topol…

Phases with non-invertible symmetries in 1+1D $\unicode{x2013}$ symmetry protected topological orders as duality automorphisms
Ãmer M. Aksoy, Xiao-Gang Wen
We explore 1+1 dimensional (1+1D) gapped phases in systems with non-invertible symmetries, focusing on symmetry-protected topological (SPT) phases (defined as gapped phases with no…

Quantum Phases and Transitions in Spin Chains with Non-Invertible Symmetries
Arkya Chatterjee, Ãmer M. Aksoy, Xiao-Gang Wen
Generalized symmetries often appear in the form of emergent symmetries in low energy effective descriptions of quantum many-body systems. Non-invertible symmetries are a particular…
