Supersymmetric multi-charge solitons in AdS$_5$

TL;DR

This paper constructs new supersymmetric soliton solutions in five-dimensional gauged supergravity with multiple charges, extending previous models, and discusses their stability properties.

Contribution

It introduces a broad class of supersymmetric multi-charge solitons in AdS$_5$, generalizing earlier $U(1)^3$ solutions, and analyzes their ergosurfaces and potential instabilities.

Findings

Solutions contain evanescent ergosurfaces

Solitons are likely nonlinearly unstable

Generalizes previous $U(1)^3$ supergravity solitons

Abstract

We construct supersymmetric, asymptotically AdS$_5$ gravitational soliton solutions of five-dimensional gauged supergravity coupled to arbitrarily many vector multiplets. These generalize the supersymmetric solitons of $U(1)^3$ gauged supergravity previously constructed by Chong, Cvetic, Lu, and Pope. We show that the solitons contain evanescent ergosurfaces and give an argument that these solitons should be nonlinearly unstable.
