Does QFT make sense in non-integer dimensions?
Diego Delmastro, Yan-Yan Li, Dikshant Rathore
We revisit the old problem of analytically continuing QFTs to fractional dimension . We observe that common theories like QCD and QED have branch cuts in the complex…
Generalized Symmetries and Deformations of Symmetric Product Orbifolds
Nathan Benjamin, Suzanne Bintanja, Yu-Jui Chen +3
We construct generalized symmetries in two-dimensional symmetric product orbifold CFTs for a generic seed CFT . These symmetries are more…
A note on entanglement entropy and topological defects in symmetric orbifold CFTs
Michael Gutperle, Yan-Yan Li, Dikshant Rathore +1
In this brief note we calculate the entanglement entropy in symmetric orbifold CFTs in the presence of topological defects, which were recently constructed in \…
Non-invertible symmetries in orbifold CFTs and holography
Michael Gutperle, Yan-Yan Li, Dikshant Rathore +1
We study non-invertible defects in two-dimensional orbifold CFTs. We construct universal defects which do not depend on the details of the seed CFT and hence exist in any orb…
Holographic 6d co-dimension 2 defect solutions in M-theory
Michael Gutperle, Nicholas Klein, Dikshant Rathore
We consider the uplift of co-dimension two defect solutions of seven dimensional gauged supergravity to eleven dimensions, previously found by two of the authors. The uplifted solu…
