AdS(3) Solutions of IIB Supergravity from D3-branes

TL;DR

This paper constructs supersymmetric AdS3 solutions in IIB supergravity from D3-branes, revealing new AdS3/CFT2 dual pairs with internal spaces as warped U(1) fibrations over Kahler manifolds.

Contribution

It introduces a class of supersymmetric AdS3 solutions with internal spaces as warped U(1) fibrations over Kahler manifolds, expanding the landscape of AdS/CFT dual pairs.

Findings

Supersymmetry constrains the internal space to a warped U(1) fibration over a Kahler manifold.

Solutions describe D3-branes with partially compactified worldvolumes leading to AdS3 factors.

Dual operators are identified as 1/8-BPS in the boundary CFT.

Abstract

We consider pure D3-brane configurations of IIB string theory which lead to supersymmetric solutions containing an AdS$_3$ factor. They can provide new examples of AdS$_3$/CFT$_2$ examples on D3-branes whose worldvolume is partially compactified. When the internal 7 dimensional space is non-compact, they can be identified as supersymmetric fluctuations of higher dimensional AdS solutions and are in general dual to 1/8-BPS operators thereof. We find that supersymmetry requires the 7 dimensional space take the form of a warped U(1) fibration over a 6 dimensional Kahler manifold.
