Complex scalar fields charged under a global U(1) symmetry can admit non-topological soliton configurations called Q-balls which are stable against decay into individual particles or smaller Q-balls. These Q-balls are interesting objects within quantum field theory, but are also of phenomenological interest in several cosmological and astrophysical contexts. The Q-ball profiles are determined by a nonlinear differential equation, and so generally require solution by numerical methods. In this work, we derive analytical approximations for the Q-ball profile in a polynomial potential and obtain simple expressions for the important Q-ball properties of charge, energy, and radius. These results improve significantly on the often-used thin-wall approximation and make it possible to describe Q-balls to excellent precision without having to solve the underlying differential equation.

Gravitational Waves From Dark Binaries With Finite-Range Dark Forces
A finite-range dark force between dark-matter binaries sharpens and enhances the predicted gravitational wave background, adding knee features tied to the mediator mass.

Hydrodynamic properties in soliton field theory
Soliton formation in complex scalar field theory is framed as sound-mode-induced phase separation, and cylindrical Q-strings are shown to suffer a Rayleigh-Plateau membrane instability that breaks them into spheres.

Q-ball perturbations with more details: linear analysis vs lattice
Q-ball perturbation theory is shown to remain valid for wavepacket amplitudes below about 10^-2 of the Q-ball background, and the analysis is extended to two-field FLS Q-balls.

Can Q-balls describe cosmological and galactic dark matter?
Q-balls made of a millicharged complex scalar field are proposed as a single dark matter candidate that behaves as CDM on cosmological scales and produces MOND-like galactic dynamics through a superfluid phase.
