TL;DR

This paper constructs smooth, horizonless extremal D1-D5-P geometries that are dual to specific CFT microstates, advancing the understanding of microstate geometries in string theory.

Contribution

It introduces a new class of extremal, smooth, horizonless solutions derived from nonextremal 3-charge backgrounds, linking them to dual CFT microstates.

Findings

Solutions are completely smooth with no horizon or singularity.

Geometries match the charges of the dual CFT microstates.

Constructs a bridge between supergravity solutions and CFT microstates.

Abstract

We construct a set of extremal D1-D5-P solutions, by taking appropriate limits in a known family of nonextremal 3-charge solutions. The extremal geometries turn out to be completely smooth, with no horizon and no singularity. The solutions have the right charges to be the duals of a family of CFT microstates which are obtained by spectral flow from the NS vacuum.
