New Supersymmetric Bubbles on AdS_3xS^3

TL;DR

This paper constructs a new class of explicit supersymmetric solutions in six-dimensional supergravity, which are asymptotic to D1-D5-P black string near-horizon geometries and potentially dual to specific BPS states in the D1-D5-P conformal field theory.

Contribution

It introduces a novel set of supersymmetric solutions based on solving a linear system on a Kahler base, expanding the known landscape of supergravity backgrounds.

Findings

Solutions preserve four supercharges.

Regular backgrounds asymptotic to D1-D5-P black string.

Potential duality to 1/4-BPS states in D1-D5-P CFT.

Abstract

We find a large new class of explicit solutions preserving four supercharges in six-dimensional supergravity. The solutions are determined by solving a linear system of equations on a four-dimensional Kahler base studied by LeBrun. For particular choices of the parameters, we find regular backgrounds that are asymptotic to the near-horizon limit of the D1-D5-P black string. Holography implies that these backgrounds should be dual to 1/4-BPS states in the D1-D5-P CFT.
