Large R-charge EFT correlators in N=2 SQCD

We consider large-R-charge Coulomb branch correlation functions in N=2 superconformal QCD in D=4 dimensions, with gauge group SU(2) and $N_f = 4$ hypermultiplets in the fundamental representation. Using information from supersymmetric recursion …

Solving the large charge expansion with integrability

S-duality and correlation functions at large R-charge

We study the ratio of pairs of adjacent correlators of Coulomb-branch operators in SU(2) N=2 SQCD with four flavors within the framework of the Large Quantum Number Expansion. Capitalizing on the order-by-order S-duality invariance of the …

Yang-Baxter deformations and generalized supergravity - A short summary

Integrable deformations of type IIB superstring theory on $\mathrm{AdS}_5\times S^5$ have played an important role over the last years. The Yang-Baxter deformation is a systematic way of generating such integrable deformations. Since its …

SUSY and the bi-vector

In this note we give an explicit formula for the preserved Killing spinors in deformed string theory backgrounds corresponding to integrable Yang-Baxter deformations realized via (sequences of) TsT transformations. The Killing spinors can be …

Killing spinors from classical r-matrices

The Yang-Baxter (YB) deformation is a systematic way of performibg integrable deformations of two-dimensional symmetric non-linear sigma models. The deformations can be labeled by classical $r$-matrices satisfying the classical YB equation. This YB …

Universal correlation functions in rank 1 SCFTs

Carrying to higher precision the large-$ \mathcal{J} $ expansion of Hellerman and Maeda, we calculate to all orders in $1/\mathcal{J}$ the power-law corrections to the two-point functions $ \mathcal{Y}\_n\equiv |x - y|^{2n\Delta\_{\mathcal{O}}} …

Extended Gauge Theory Deformations From Flux Backgrounds

We consider supersymmetric deformations of gauge theories in various dimensions obtained from a String Theory realisation of branes embedded in flux backgrounds. In particular we obtain deformations which take the form of Wilson line defects, where …

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 …
