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…

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…
