Ferromagnetic properties of charged vector bosons condensate in the early universe

TL;DR

This paper investigates how Bose-Einstein condensation of charged vector bosons in the early universe can lead to spontaneous magnetization, potentially explaining the origin of primordial magnetic fields.

Contribution

It introduces the concept that a condensate of charged vector bosons can form a ferromagnetic state in the early universe, leading to primordial magnetic field generation.

Findings

A ferromagnetic state forms in the charged vector boson condensate.

The primeval plasma can spontaneously magnetize within large domains.

Primordial magnetic fields can originate from this ferromagnetic condensate.

Abstract

Bose-Einstein condensation in the early universe is considered. The magnetic properties of a condensate of charged vector bosons are studied, showing that a ferromagnetic state is formed. As a consequence, the primeval plasma may be spontaneously magnetized inside macroscopically large domains and primordial magnetic fields can be generated.
