Charged black strings in 5D Kaluza-Klein spacetime

TL;DR

This paper reviews charged black strings in five-dimensional Kaluza-Klein spacetime, analyzing their stability properties and how electric and magnetic charges influence their stability.

Contribution

It provides a comparative stability analysis of electric and magnetic black strings in 5D Kaluza-Klein spacetime, highlighting the differing effects of charge types.

Findings

Electric black strings are less stable than neutral ones.

Magnetic black strings are more stable than electric ones.

Presence of charge affects the stability thresholds of black strings.

Abstract

We present a short review on the electric and magnetic black strings in 5D spacetime with one compact dimension. Linear static perturbations of these objects indicate presence of the threshold unstable mode. Analysis of the mode shows that the electric black string is less stable than a neutral one. The situation is opposite for the magnetic black string.
