Q-stars in anti de Sitter spacetime

TL;DR

This paper investigates q-star solitons in anti de Sitter spacetime, analyzing their properties, phase space, and stability, revealing how the spacetime curvature influences their characteristics compared to flat spacetime.

Contribution

It provides a detailed analysis of q-stars in AdS spacetime, including effects of symmetry, charge, and stability, which were not previously explored in this context.

Findings

Field value at the center is larger in AdS than in flat spacetime.

Symmetry type affects the phase space and stability of q-stars.

Charge influences the stability and phase structure of the solitons.

Abstract

We study q-stars with various symmetries in anti de Sitter spacetime in 3+1 dimensions. Comparing with the case of flat spacetime, we find that the value of the field at the center of the soliton is larger when the other parameters show a more complicated behavior. We also investigate their phase space when the symmetry is local and the effect of the charge to its stability.
