In this paper we continue our investigation of the global categorical symmetries that arise when gauging finite higher groups and their higher subgroups with discrete torsion. The motivation is to provide a common perspective on the construction of n... Read More about Non-invertible symmetries and higher representation theory II.

The purpose of this paper is to investigate the global categorical symmetries that arise when gauging finite higher groups in three or more dimensions. The motivation is to provide a common perspective on constructions of non-invertible global symmet... Read More about Non-invertible symmetries and higher representation theory I.

Generalized symmetries and anomalies of 3d N = 4 SCFTs (2024)
Journal Article
Bhardwaj, L., Bullimore, M., Ferrari, A. E. V., & Schäfer-Nameki, S. (2024). Generalized symmetries and anomalies of 3d N = 4 SCFTs. SciPost Physics, 16(3), Article 080. https://doi.org/10.21468/scipostphys.16.3.080

We study generalized global symmetries and their 't Hooft anomalies in 3d N=4 superconformal field theories (SCFTs). Following some general considerations, we focus on good quiver gauge theories, comprised of balanced unitary nodes and unbalanced uni...
