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…
