Non-invertible defects on the worldsheet
Sriram Bharadwaj, Pierluigi Niro, Konstantinos Roumpedakis
We consider codimension-one defects in the theory of compact scalars on a two-dimensional worldsheet, acting linearly by mixing the scalars and their duals. By requiring that t…

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…
