Maxwell-Higgs vortices with internal structure

TL;DR

This paper explores Maxwell-Higgs vortices interacting with a neutral scalar field, introducing internal structures to the vortices by modifying the standard solutions through generalized permeability and first order equations.

Contribution

It presents a novel approach to vortex solutions by incorporating a neutral scalar field and generalized permeability, leading to vortices with internal structure.

Findings

Vortices with internal structure are achievable in Maxwell-Higgs systems.

Neutral scalar fields influence vortex core properties.

Modified solutions extend standard vortex models.

Abstract

Vortices are considered in relativistic Maxwell-Higgs systems in interaction with a neutral scalar field. The gauge field interacts with the neutral field via the presence of generalized permeability, and the charged and neutral scalar fields interact in a way dictated by the presence of first order differential equations that solve the equations of motion. The neutral field may be seen as the source field of the vortex, and we study some possibilities, which modify the standard Maxwell-Higgs solution and include internal structure to the vortex.
