Non-invertible symmetries and higher representation theory II (2024)
Journal Article
Bartsch, T., Bullimore, M., Ferrari, A. E. V., & Pearson, J. (2024). Non-invertible symmetries and higher representation theory II. SciPost Physics, 17(2), Article 067. https://doi.org/10.21468/scipostphys.17.2.067

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.

Non-invertible symmetries and higher representation theory I (2024)
Journal Article
Bartsch, T., Bullimore, M., Ferrari, A. E. V., & Pearson, J. (2024). Non-invertible symmetries and higher representation theory I. SciPost Physics, 17(1), Article 015. https://doi.org/10.21468/scipostphys.17.1.015

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.

Anomalies of generalized symmetries from solitonic defects (2024)
Journal Article
Bhardwaj, L., Bullimore, M., Ferrari, A. E. V., & Schäfer-Nameki, S. (2024). Anomalies of generalized symmetries from solitonic defects. SciPost Physics, 16, Article 087. https://doi.org/10.21468/scipostphys.16.3.087

We propose the general idea that ’t Hooft anomalies of generalized global symmetries can be understood in terms of the properties of solitonic defects, which generically are nontopological defects. The defining property of such defects is that they a... Read More about Anomalies of generalized symmetries from solitonic defects.

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...
