Deconstruction and surface defects in 6d CFTs

TL;DR

This paper explores two classes of AdS$_3$ solutions in massive Type IIA supergravity, proposing their dualities to 6d (1,0) CFTs and surface defects, based on holographic analysis of various observables.

Contribution

It introduces a holographic interpretation of two families of AdS$_3$ solutions as dual to 6d (1,0) CFTs and their surface defects, expanding understanding of these dualities.

Findings

First class solutions dual to deconstructed 6d (1,0) CFTs.

Second class solutions represent surface defects in 6d theories.

Analysis of baryon vertices and giant gravitons supports the duality interpretations.

Abstract

We study the two families of AdS$_3\times S^3\times S^2\times \Sigma_2$ solutions to massive Type IIA supergravity with small and large $(0,4)$ supersymmetries constructed recently in the literature, in connection with the AdS$_7\times S^2\times I$ solutions to massive Type IIA, to which they asymptote locally. Based on our analysis of various observables, that we study holographically, we propose an interpretation of the first class of solutions as dual to deconstructed 6d (1,0) CFTs dual to AdS$_7$, and of the second class as dual to surface defects in the same 6d theories. Among the observables that we study are baryon vertices and giant graviton configurations in quiver-like constructions.
