Fluids of Vortices And Dark Matter

TL;DR

This paper develops a model of a fluid of vortices based on Abelian-Higgs string solutions, proposing a modified gravitational dynamics that could explain dark matter phenomena.

Contribution

It introduces a novel fluid of vortices model derived from Abelian-Higgs strings, extending the fluid of strings concept to incorporate vortex solutions for modified gravity.

Findings

Quantitative analysis of modified dynamics for a static spherical vortex fluid.

Proposal of a vortex-based fluid model as a dark matter candidate.

Extension of Milgrom's modified gravity framework using vortex fluids.

Abstract

By considering full-field string solutions of the Abelian--Higgs model, we modify the model of a fluid of strings (which is composed of Nambu strings) to obtain a model for a ``fluid of vortices.'' With this model, and following closely Soleng's proposal of a fluid of strings as the source of a Milgrom-type correction to the Newton dynamics, we determine quantitatively the modified dynamics generated by a static, spherical fluid of vortices.
