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…
"Symmetry-from-Anomaly" in Condensed Matter related Constructions
Cenke Xu
The noninvertible axial symmetry constructed from the ABJ-anomaly has attracted enormous interest. We discuss the mechanism of "symmetry-from-anomaly" in condensed matter-related m…
Symmetry protected topological phases under decoherence
Jong Yeon Lee, Yi-Zhuang You, Cenke Xu
We study ensembles described by density matrices with potentially nontrivial topological features. In particular, we study a class of symmetry protected topological (SPT) phases un…
Higher-form Symmetries under Weak Measurement
Kaixiang Su, Nayan Myerson-Jain, Chong Wang +2
We aim to address the following question: if we start with a quantum state with a spontaneously broken higher-form symmetry, what is the fate of the system under weak local quantum…
