TL;DR

This paper constructs smooth, horizonless microstate geometries of the supersymmetric D1-D5-P black hole in six-dimensional supergravity, featuring vector field momentum, and explores their holographic duals and string theory implications.

Contribution

It introduces new vector superstrata solutions with momentum carried by vector fields, extending microstate geometry constructions and connecting them to string theory frameworks.

Findings

Geometries are smooth, horizonless, asymptotically AdS3×S3 with an AdS2 throat.

Existence of a frame where solutions are in the NS-sector, facilitating string theory analysis.

Proposed holographic duals for the constructed microstate geometries.

Abstract

We present the construction of several microstate geometries of the supersymmetric D1-D5-P black hole in which, within six-dimensional supergravity, the momentum charge is carried by a vector field. The fully backreacted geometries are smooth and horizonless: They are asymptotically AdS$_3 \times S^3$ with an AdS$_2$ throat that smoothly caps off. We propose a holographic dual for these bulk solutions and discuss their extension to asymptotically flat space. In addition, we present several uplifts of the full six-dimensional supersymmetric ansatz to ten-dimensions. In particular, we show that there exists a frame in which geometries based on vector field momentum carriers are entirely in the NS-sector of supergravity, making them possible starting points for the exploration of stringy black-hole microstates.
