Remarks on Associated Varieties and Minimal Tension Holography
Andrea E. V. Ferrari
We comment on certain analogies that have recently emerged between path integral localisation phenomena in minimal tension string theory on and…
3d Mirror Symmetry, TQFTs, and 't Hooft Anomaly Matching
Mahesh K. N. Balasubramanian, Anindya Banerjee, Matthew Buican +3
Any local unitary 3d superconformal field theory (SCFT) has a corresponding "universal" relevant deformation that takes it to a gapped phase. This deformation prese…
Boundary vertex algebras for 3d rank-0 SCFTs
Andrea E. V. Ferrari, Niklas Garner, Heeyeon Kim
We initiate the study of boundary Vertex Operator Algebras (VOAs) of topologically twisted 3d rank-0 SCFTs. This is a recently introduced class of S…
Free field realisation of boundary vertex algebras for Abelian gauge theories in three dimensions
Christopher Beem, Andrea E. V. Ferrari
We study the boundary vertex algebras of -twisted Abelian gauge theories in three dimensions. These are identified with the BRST quotient (semi-infinite cohomolo…
Generalized Symmetries and Anomalies of 3d N=4 SCFTs
Lakshya Bhardwaj, Mathew Bullimore, Andrea E. V. Ferrari +1
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…
Non-invertible Symmetries and Higher Representation Theory II
Thomas Bartsch, Mathew Bullimore, Andrea E. V. Ferrari +1
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…
Non-invertible Symmetries and Higher Representation Theory I
Thomas Bartsch, Mathew Bullimore, Andrea E. V. Ferrari +1
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…
Anomalies of Generalized Symmetries from Solitonic Defects
Lakshya Bhardwaj, Mathew Bullimore, Andrea E. V. Ferrari +1
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 non-to…
Supersymmetric ground states of 3d SUSY gauge theories and Heisenberg Algebras
Andrea E. V. Ferrari
We consider 3d theories on the geometry , where is a closed and connected Riemann surface, from the point of view of a quantum mechanics on…
Supersymmetric Ground States of 3d Gauge Theories on a Riemann Surface
Mathew Bullimore, Andrea E. V. Ferrari, Heeyeon Kim
This paper studies supersymmetric ground states of 3d supersymmetric gauge theories on a Riemann surface of genus . There are two distinct spaces of supersymmetr…
The Twisted Index and Topological Saddles
Mathew Bullimore, Andrea E. V. Ferrari, Heeyeon Kim +1
The twisted index of 3d gauge theories on has an algebro-geometric interpretation as the Witten index of an effective supersymmetric quantum mechanic…
The 3d Twisted Index and Wall-Crossing
Mathew Bullimore, Andrea E. V. Ferrari, Heeyeon Kim
We study the twisted index of 3d supersymmetric gauge theories on in the presence of a real FI parameter deformation. This parameter induces a 1d FI…
Twisted Indices of 3d Gauge Theories and Enumerative Geometry of Quasi-Maps
Mathew Bullimore, Andrea E. V. Ferrari, Heeyeon Kim
We explore the geometric interpretation of the twisted index of 3d gauge theories on where is a closed Riemann surface. We focus on a rich class…
Twisted Hilbert Spaces of 3d Supersymmetric Gauge Theories
Mathew Bullimore, Andrea E. V. Ferrari
We study aspects of 3d supersymmetric gauge theories on the product of a line and a Riemann surface. Performing a topological twist along the Riemann surface leads…
