3-charge geometries and their CFT duals

TL;DR

This paper constructs smooth gravity duals for specific D1-D5-P states, supporting the idea that black hole interiors are nontrivial up to the horizon, with no horizons or closed timelike curves.

Contribution

It provides explicit smooth geometries for D1-D5-P states, advancing the understanding of black hole microstates and their dual descriptions.

Findings

Geometries cap off smoothly near r=0

No horizons or closed timelike curves found

Supports the conjecture of nontrivial black hole interiors

Abstract

We consider two families of D1-D5-P states and find their gravity duals. In each case the geometries are found to `cap off' smoothly near r=0; thus there are no horizons or closed timelike curves. These constructions support the general conjecture that the interior of black holes is nontrivial all the way up to the horizon.
