W-algebras of the Deligne-Cvitanović Exceptional series and the minimal 3d SCFT
Thomas Creutzig, Niklas Garner, Byeonggi Go +1
We propose a three-dimensional field theory construction that realizes the vertex algebras associated with the intermediate Lie algebras and the related -cofinite minimal -…
Unravelling the Holomorphic Twist II: Anomalies and Extended Supersymmetry
Pieter Bomans, Niklas Garner, Brian R. Williams +1
Twists of four-dimensional supersymmetric quantum field theories (SQFTs) isolate protected sectors with rich algebraic structures. We develop a unified framework for analyzing symm…
On the semi-infinite cohomology of graded-unitary vertex algebras
Christopher Beem, Niklas Garner
Recently, the first author with A. Ardehali, M. Lemos, and L. Rastelli introduced the notion of graded unitarity for vertex algebras. This generalization of unitarity is motivated…
Higgs and coulomb branches from superconformal raviolo vertex algebras
Niklas Garner, Surya Raghavendran, Brian R. Williams
We propose a method for extracting the Higgs and Coulomb branches of a three-dimensional N = 4 quantum field theory from the algebra of local operators in its holomorphic-topologic…
Enhanced symmetries in minimally-twisted three-dimensional supersymmetric theories
Niklas Garner, Surya Raghavendran, Brian R. Williams
We show that the action of residual supersymmetries in holomorphic-topological twists of theories in three dimensions naturally extends to the action of certain infinite di…
