Peeling off Abelian Anyons and Proliferation Transitions
Meng Cheng, Nathan Seiberg
We study the invertible one-form global symmetry of a (2+1)-dimensional topological quantum field theory (TQFT). A universal description of this symmetry ``peels off'' all the Abel…
Note on proliferation transitions of non-Abelian anyons
Meng Cheng
We study phase transitions out of a (2+1)d topological phase driven by the proliferation of anyons in a braided fusion subcategory. We describe a general theoretical framework for…
Lieb-Schultz-Mattis Anomalies and Anomaly Matching
Liujun Zou, Meng Cheng
Lieb-Schultz-Mattis (LSM) anomalies are powerful symmetry-based constraints on the correlation, entanglement and dynamics of quantum many-body systems. In this review, we discuss v…
Proliferation transitions from a topological phase in dimensions
Meng Cheng, Nathan Seiberg
We consider phase transitions out of a general topological phase in dimensions. We assume that the transition is triggered by a single Abelian anyon, which becomes light near…
