Randall-Sundrum Scenario at Nonzero Temperature

TL;DR

This paper explores how introducing nonzero temperature affects the Randall-Sundrum brane-world model, revealing that key symmetries like $Z_2$ are broken at finite temperature, which impacts the model's properties.

Contribution

It demonstrates that nonzero temperature alters fundamental features of the Randall-Sundrum scenario, including symmetry properties, using a spacetime ansatz inspired by AdS/CFT correspondence.

Findings

$Z_2$ symmetry is broken at nonzero temperature

Model features change with temperature

Temperature effects influence brane-world properties

Abstract

The effect of temperature is investigated in the Randall-Sundrum brane-world scenario. It is shown that for a spacetime ansatz motivated by similarity with AdS/CFT correspondence several features of the model, such as its $Z_2$ symmetry, are not maintained at nonzero temperatures.
