On supersymmetry enhancements in three dimensions
Benjamin Assel, Yuji Tachikawa, Alessandro Tomasiello
We introduce a class of 3d theories consisting of strongly-coupled systems coupled to Chern-Simons gauge multiplets, which exhibit ${\mathcal N}=4…
Quantized Coulomb Branches, Monopole Bubbling and Wall-Crossing Phenomena in 3d Theories
Benjamin Assel, Stefano Cremonesi, Matthew Renwick
To study the quantized Coulomb branch of 3d unitary SQCD theories, we propose a new method to compute correlators of monopole and Casimir operators that are inserte…
On Monopole Bubbling Contributions to 't Hooft Loops
Benjamin Assel, Antonio Sciarappa
Monopole bubbling contributions to supersymmetric 't Hooft loops in 4d theories are computed by SQM indices. As recently argued, those indices are hard to compute d…
Note on Monopole Operators in Chern-Simons-Matter Theories
Benjamin Assel
Monopole operators in Chern-Simons theories with charged matter have been studied using the state-operator map in CFTs, as states on with background magnetic…
Wilson loops in 5d theories and S-duality
Benjamin Assel, Antonio Sciarappa
We study the action of S-duality on half-BPS Wilson loop operators in 5d theories. The duality is the statement that different massive deformations of a single 5d S…
Holographic duals of 3d S-fold CFTs
Benjamin Assel, Alessandro Tomasiello
We construct non-geometric AdS solutions of IIB string theory where the fields in overlapping patches are glued by elements of the S-duality group. We obtain them by suitable q…

We study the complete moduli space of vacua of 3d SQCD theories with fundamentals, building on the algebraic description of the Coulomb branch, and ded…
The Space of Vacua of 3d Abelian Theories
Benjamin Assel
We use brane techniques to study the space of vacua of abelian 3d gauge theories. The coordinates on these spaces are the vevs of chiral monopole and meson operator…

We study the space of vacua of three-dimensional theories from a novel approach building on the type IIB brane realization of the theory and in which the insertion…
Six-dimensional Origin of SYM with Duality Defects
Benjamin Assel, Sakura Schafer-Nameki
We study the topologically twisted compactification of the 6d M5-brane theory on an elliptically fibered Kähler three-fold preserving two supercharges. We show that upon re…
Localization of supersymmetric field theories on non-compact hyperbolic three-manifolds
Benjamin Assel, Dario Martelli, Sameer Murthy +1
We study supersymmetric gauge theories with an R-symmetry, defined on non-compact, hyperbolic, Riemannian three-manifolds, focusing on the case of a supersymmetry-preserving quotie…
M5-branes on S^2 x M_4: Nahm's Equations and 4d Topological Sigma-models
Benjamin Assel, Sakura Schafer-Nameki, Jin-Mann Wong
We study the 6d N=(0,2) superconformal field theory, which describes multiple M5-branes, on the product space S^2 x M_4, and suggest a correspondence between a 2d N=(0,2) half-twis…
Mirror Symmetry And Loop Operators
Benjamin Assel, Jaume Gomis
Wilson loops in gauge theories pose a fundamental challenge for dualities. Wilson loops are labeled by a representation of the gauge group and should map under duality to loop oper…
