Unitarity Method for Holographic Defects

Junding Chen, Aleix Gimenez-Grau, Hynek Paul +1

We initiate the study of loop-level holographic correlators in the presence of defects. We present a unitarity method which constructs loop corrections from lower order data. As an…

Analytic bootstrap for magnetic impurities

Lorenzo Bianchi, Davide Bonomi, Elia de Sabbata +1

We study the critical model and the free theory of a scalar triplet in the presence of a magnetic impurity. We use analytic bootstrap techniques to extract results in the $\…

Defect two-point functions in 6d (2,0) theories

Junding Chen, Aleix Gimenez-Grau, Xinan Zhou

We consider correlation functions in 6d theories of two -BPS operators inserted away from a -BPS surface defect. In the large central charge limit…

Scale without Conformal Invariance in Dipolar Ferromagnets

Aleix Gimenez-Grau, Yu Nakayama, Slava Rychkov

We revisit critical phenomena in isotropic ferromagnets with strong dipolar interactions. The corresponding RG fixed point - dipolar fixed point - was first studied in 1973 by Ahar…

The Witten Diagram Bootstrap for Holographic Defects

Aleix Gimenez-Grau

We study the AdS/CFT correspondence with a brane extending in AdS, a setup which is dual to CFT in the presence of a defect. We focus on the correlation function of two local opera…

Probing magnetic line defects with two-point functions

Aleix Gimenez-Grau

This paper studies magnetic line defects in the Wilson-Fisher model. A powerful method to probe the system is to consider mixed two-point functions of the order parameter an…

Bootstrapping line defects with global symmetry

Aleix Gimenez-Grau, Edoardo Lauria, Pedro Liendo +1

We use the numerical bootstrap to study conformal line defects with global symmetry. Our results are very general and capture in particular conformal line defects originatin…

A dispersion relation for defect CFT

Julien Barrat, Aleix Gimenez-Grau, Pedro Liendo

We present a dispersion relation for defect CFT that reconstructs two-point functions in the presence of a defect as an integral of a single discontinuity. The main virtue of this…

Bootstrapping holographic defect correlators in super Yang-Mills

Julien Barrat, Aleix Gimenez-Grau, Pedro Liendo

We study two-point functions of single-trace half-BPS operators in the presence of a supersymmetric Wilson line in SYM. We use inversion formula technology in order…

Bootstrapping Monodromy Defects in the Wess-Zumino Model

Aleix Gimenez-Grau, Pedro Liendo

We use analytical bootstrap techniques to study supersymmetric monodromy defects in the critical Wess-Zumino model. In preparation for this result we first study two related system…

Superconformal Boundaries in dimensions

Aleix Gimenez-Grau, Pedro Liendo, Philine van Vliet

Boundaries in three-dimensional superconformal theories may preserve one half of the original bulk supersymmetry. There are two possibilities which are characterize…

Bootstrapping Coulomb and Higgs branch operators

Aleix Gimenez-Grau, Pedro Liendo

We apply the numerical conformal bootstrap to correlators of Coulomb and Higgs branch operators in superconformal theories. We start by revisiting previous res…

A Quantum Framework for AdS/dCFT through Fuzzy Spherical Harmonics on

Aleix Gimenez-Grau, Charlotte Kristjansen, Matthias Volk +1

We consider a non-supersymmetric domain-wall version of SYM theory where five out of the six scalar fields have non-zero classical values on one side of a wall of…

Bootstrapping line defects in theories

Aleix Gimenez-Grau, Pedro Liendo

We study half-BPS line defects in superconformal theories using the bootstrap approach. We concentrate on local excitations constrained to the defect, which means t…
