Non-Invertible Duality Defects in 3+1 Dimensions
Yichul Choi, Clay Cordova, Po-Shen Hsin +2
For any quantum system invariant under gauging a higher-form global symmetry, we construct a non-invertible topological defect by gauging in only half of spacetime. This generalize…
Anomaly Inflow for Subsystem Symmetries
Fiona J. Burnell, Trithep Devakul, Pranay Gorantla +2
We study 't Hooft anomalies and the related anomaly inflow for subsystem global symmetries. These symmetries and anomalies arise in a number of exotic systems, including models wit…
The low-energy limit of some exotic lattice theories and UV/IR mixing
Pranay Gorantla, Ho Tat Lam, Nathan Seiberg +1
We continue our exploration of exotic, gapless lattice and continuum field theories with subsystem global symmetries. In an earlier paper, we presented free lattice models enjoying…
A Modified Villain Formulation of Fractons and Other Exotic Theories
Pranay Gorantla, Ho Tat Lam, Nathan Seiberg +1
We reformulate known exotic theories (including theories of fractons) on a Euclidean spacetime lattice. We write them using the Villain approach and then we modify them to a conven…
