Critical phenomena of gravitating monopoles in the spacetime of a global monopole

TL;DR

This paper numerically investigates critical phenomena, including the Lue-Weinberg phenomenon, in gravitating monopoles within a global monopole spacetime, expanding understanding of their behavior near critical points.

Contribution

It provides new numerical insights into the critical phenomena of gravitating monopoles in global monopole spacetimes, focusing on phenomena previously studied analytically or numerically in limited parameter regions.

Findings

Identification of critical phenomena including Lue-Weinberg phenomenon

Numerical characterization of monopole behavior near critical points

Extension of previous studies to broader parameter space

Abstract

We present a numerical study of critical phenomena (including the Lue-Weinberg phenomenon) arising for gravitating monopoles in a global monopole spacetime. The equations of this model have been recently studied by Spinelly et al. in a domain of parameter space away from the critical points.
