On ${\mathcal N}=4$ supersymmetry enhancements in three dimensions Open
We introduce a class of 3d theories consisting of strongly-coupled ${\mathcal N}=4$ systems coupled to ${\mathcal N}=3$ Chern-Simons gauge multiplets, which exhibit ${\mathcal N}=4$ enhancements when a peculiar condition on the Chern-Simon…
Note on monopole operators in Chern-Simons-matter theories Open
A bstract Monopole operators in Chern-Simons theories with charged matter have been studied using the state-operator map in CFTs, as states on ℝ × S 2 with background magnetic flux on S 2 . Gauge invariance requires a dressing with matter …
Note on Monopole Operators in Chern-Simons-Matter Theories Open
Monopole operators in Chern-Simons theories with charged matter have been studied using the state-operator map in CFTs, as states on $\mathbb{R}\times S^2$ with background magnetic flux on $S^2$. Gauge invariance requires a dressing with m…
Report on 1809.06272v2 Open
We construct gauge theories with a vector-multiplet and hypermultiplets of (1, 0) supersymmetry on the six-sphere.The gauge coupling on the sphere depends on the polar angle.This has a natural explanation in terms of the tensor branch of (…
Holographic duals of 3d S-fold CFTs Open
A bstract We construct non-geometric AdS 4 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 quotients of compact and non-compact geometric solut…
Report on 1707.03403v2 Open
We study the complete moduli space of vacua of 3d N = 4 U (N ) SQCD theories with N f fundamentals, building on the algebraic description of the Coulomb branch, and deduce the low energy physics in any vacuum from the local geometry of the…
