Mirror Symmetry and Level-rank Duality for 3d Rank 0 SCFTs
Thomas Creutzig, Niklas Garner, Heeyeon Kim
We introduce a family of 3d superconformal field theories that have zero-dimensional Coulomb and Higgs branches and propose that the rational vertex operator alge…
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…
Raviolo vertex algebras
Niklas Garner, Brian R. Williams
We develop an algebraic structure modeling local operators in a three-dimensional quantum field theory which is partially holomorphic and partially topological. The geometric space…
Twistorial monopoles & chiral algebras
Niklas Garner, Natalie M. Paquette
We initiate the study of how the insertion of magnetically charged states in 4d self-dual gauge theories impacts the 2d chiral algebras supported on the celestial sphere at asympto…
Line Operators in Chern-Simons Theory
Niklas Garner, Wenjun Niu
We analyze the non-semisimple category of line operators in Chern-Simons gauge theories based off the Lie superalgebra . Our proposal is that the category of li…
TASI Lectures on the Mathematics of String Dualities
Niklas Garner, Natalie M. Paquette
In these lecture proceedings, we describe some of the fundamental mathematical concepts that underlie supersymmetric string theory and field theory, and their role in describing an…
Twisted Formalism for 3d Theories
Niklas Garner
We describe the topological and twists of 3d theories of hypermultiplets gauged by vector multiplets as certain deformations of the holomorp…
Vertex Operator Algebras and Topologically Twisted Chern-Simons-Matter Theories
Niklas Garner
We consider several topologically twisted Chern-Simons-matter theories and propose boundary VOAs whose module categories should model the category of line operators of the 3d bulk.…
A QFT for non-semisimple TQFT
Thomas Creutzig, Tudor Dimofte, Niklas Garner +1
We construct a family of 3d quantum field theories that conjecturally provide a physical realization -- and derived generalization -- of non-semisimple mathema…
Generalized affine Springer theory and Hilbert schemes on planar curves
Niklas Garner, Oscar Kivinen
We show that Hilbert schemes of planar curve singularities and their parabolic variants can be interpreted as certain generalized affine Springer fibers for , as defined by G…
Mirror symmetry and line operators
Tudor Dimofte, Niklas Garner, Michael Geracie +1
We study half-BPS line operators in 3d N=4 gauge theories, focusing in particular on the algebras of local operators at their junctions. It is known that there are two basic types…
Coulomb Branches of Star-Shaped Quivers
Tudor Dimofte, Niklas Garner
We study the Coulomb branches of 3d N=4 `star-shaped' quiver gauge theories and their deformation quantizations, by applying algebraic techniques that have been developed in the ma…
