“…However, for b = 0, 1 we find an interacting theory: N = 4 SQED with two flavors. This agrees with the finding of [29,30]: there are two singular points on the CB at which the low energy effective action is T (SU (2)). At all other points the effective theory is a twisted hypermultiplet.…”

“…deformed to the known mirror duals of both N = 4 and N = 2 SQCD (hence can be considered the mirror dual of adjoint SQCD) and allows to understand the infrared properties of the so-called bad N = 4 theories (in the language of [26]) with simple field-theoretic manipulations (our results are in perfect agreement with the findings of [27][28][29][30]). As a further test of our construction, in Section 4 we use our proposal to recover the "duality appetizer" of [31].…”

In this paper we study dualities for N = 2 gauge theories in three dimensions with matter in the fundamental and adjoint representation. The duality we propose, analogous to mirror symmetry, is obtained starting from N = 4 mirror theories and turning on a certain superpotential deformation involving monopole operators. We study the role of emergent symmetries in the dual theory, focusing on the case of models with gauge symmetry U (2) or SU (2). We find that SU (2) adjoint SQCD with one flavor and zero superpotential is dual to SQED with two flavors and three singlets. As a byproduct, we recover several dualities for theories with N = 2 and N = 4 supersymmetry, including the duality appetizer of Jafferis and Yin.

“…There exists another trick to access bubbling terms in SU (2) (and more generally, in SU (N )) gauge theory. It consists of studying the U (2) theory first, and then gauging the U (1) top symmetry that rotates the dual photon in the diagonal U (1) gauge group (this approach was also used in [48,49]). In a U (2) gauge theory, monopole charges are labeled by two integers (n, m) ∈ Z 2 , and some of them are minuscule.…”

We develop an approach to the study of Coulomb branch operators in 3D N = 4 gauge theories and the associated quantization structure of their Coulomb branches. This structure is encoded in a one-dimensional TQFT subsector of the full 3D theory, which we describe by combining several techniques and ideas. The answer takes the form of an associative and noncommutative star product algebra on the Coulomb branch. For "good" and "ugly" theories (according to the Gaiotto-Witten classification), we also exhibit a trace map on this algebra, which allows for the computation of correlation functions and, in particular, guarantees that the star product satisfies a truncation condition. This work extends previous work on abelian theories to the non-abelian case by quantifying the monopole bubbling that describes screening of GNO boundary conditions. In our approach, monopole bubbling is determined from the algebraic consistency of the OPE. This also yields a physical proof of the Bullimore-Dimofte-Gaiotto abelianization description of the Coulomb branch.

“…This approach was also used in[39] to analyse the Coulomb branch of SU (2) SCQD theories with two and four flavours 25. Shifting the level of the moment map to Φ 1 = µ can be undone by an appropriate redefinition.…”

We derive the algebraic description of the Coulomb branch of 3d N = 4 US p(2N ) SQCD theories with N f fundamental hypermultiplets and determine their low energy physics in any vacuum from the local geometry of the moduli space, identifying the interacting SCFTs which arise at singularities and possible extra free sectors. The SCFT with the largest moduli space arises at the most singular locus on the Coulomb branch. For N f > 2N (good theories) it sits at the origin of the conical variety as expected. For N f = 2N we find two separate most singular points, from which the two isomorphic components of the Higgs branch of the UV theory emanate. The SCFTs sitting at any of these two vacua have only odd dimensional Coulomb branch generators, which transform under an accidental SU(2) global symmetry. We provide a direct derivation of their moduli spaces of vacua, and propose a Lagrangian mirror theory for these fixed points. For 2 ≤ N f < 2N the most singular locus has one or two extended components, for N f odd or even, and the low energy theory involves an interacting SCFT of one of the above types, plus free twisted hypermultiplets. For N f = 0, 1 the Coulomb branch is smooth. We complete our analysis by studying the low energy theory at the symmetric vacuum of theories with N < N f ≤ 2N , which exhibits a local Seiberg-like duality.
