## An AdS/EFT correspondence at large charge

Considering theories in sectors of large global charge $Q$ results in a semiclassical effective field theory (EFT) description for some strongly-coupled conformal field theories (CFTs) with continuous global symmetries. Hence, when studying dualities …

## Deformations, defects and a noncommutative spectral curve

The fluxtrap is an exact string theory background that has been originally introduced as a string realization of the $\Omega$ deformation. The background can be completely captured, via a Seiberg-Witten map, by a noncommutative deformation of flat …

## Monopole Quivers and new 3D N=2 dualities

We present a new family of dualities for three-dimensional gauge theories, motivated by the brane realization of the reduction of four-dimensional dualities on a circle. This family can be understood as a generalization of Aharony duality to quiver …

## String theory and the 4D/3D reduction of Seiberg duality. A Review

We review the reduction of four-dimensional N=1 Seiberg duality to three dimensions focusing on the D brane engineering approach. We start with an overview of four-dimensional Seiberg duality for theories with various types of gauge groups and matter …

## 4D/3D reduction of dualities: mirrors on the circle

We engineer a brane picture for the reduction of Seiberg dualities from four dimensions to three dimensions, valid also in the presence of orientifold planes. We obtain effective three-dimensional dualities on the circle by T-duality, geometrizing …
