Radionic Non-uniform Black Strings --short version--

TL;DR

This paper investigates non-uniform black strings in a two-brane system, revealing the radion as a non-trivial hair and demonstrating their stability and non-uniformity through effective action and catastrophe theory.

Contribution

It introduces the radion as a new non-trivial hair for black strings and analyzes their stability and non-uniformity using effective action and catastrophe theory.

Findings

Radion acts as a non-trivial hair for black strings

Black strings are shown to be non-uniform

Solutions are demonstrated to be stable

Abstract

Non-uniform black strings in the two-brane system are investigated using the effective action approach. It is shown that the radion acts as a non-trivial hair of black strings. The stability of solutions is demonstrated using the catastrophe theory. The black strings are shown to be non-uniform.
