Eugen Radu, Mihai Visinescu
TL;DR
This paper studies solutions to the Klein-Gordon equation within five-dimensional geometries that resemble the Gross-Perry-Sorkin monopole, including regular and black hole backgrounds, to understand quantum field behavior in these exotic spacetimes.
Contribution
It analyzes the Klein-Gordon equation in generalized Kaluza-Klein monopole backgrounds, extending previous work to include black hole solutions and regular geometries.
Findings
Solutions characterized in monopole-like geometries
Behavior of scalar fields in black hole backgrounds
Insights into quantum fields in higher-dimensional spacetimes
Abstract
We investigate solutions of the Klein-Gordon equation in a class of five dimensional geometries presenting the same symmetries and asymptotic structure as the Gross-Perry-Sorkin monopole solution. Apart from globally regular metrics, we consider also squashed Kaluza-Klein black holes backgrounds.
