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…
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…
Tori, Klein Bottles, and Modulo 8 Parity/Time-reversal Anomalies of 2+1d Staggered Fermions
Nathan Seiberg, Wucheng Zhang
We study the symmetries of lattice staggered fermions in 2+1d. Using the symmetries, we can place the system on any sheared torus or Klein bottle. These different backgrounds provi…
LSM and CPT
Nathan Seiberg, Shu-Heng Shao, Wucheng Zhang
We study a number of 1+1d lattice models with anti-unitary symmetries that simultaneously reflect space and reverse time. Some of these symmetries are anomalous, leading to Lieb-Sc…
Ordering the topological order in the fractional quantum Hall effect
Meng Cheng, Seth Musser, Amir Raz +2
We discuss the possible topological order/topological quantum field theory of different quantum Hall systems. Given the value of the Hall conductivity, we constrain the global symm…
Symmetry Transmutation and Anomaly Matching
Nathan Seiberg, Sahand Seifnashri
We explore a situation where a global symmetry of the ultraviolet (UV) theory does not act faithfully on the local infrared (IR) degrees of freedom, but instead acts effectively as…
