# Condensation of neutral vector bosons with magnetic moment

## TL;DR

This paper investigates how neutral vector bosons with magnetic moments behave under strong magnetic fields, showing they can condense and sustain magnetic fields, with implications for astrophysics.

## Contribution

It introduces a model for neutral vector bosons with magnetic moments, revealing their condensation and self-sustaining magnetic fields under certain conditions.

## Key findings

- Effective mass decreases with magnetic field strength.
- Boson condensation occurs below a critical magnetic field.
- System can maintain a self-consistent magnetic field.

## Abstract

We study the equation of motion of neutral vector bosons bearing a magnetic moment (MM). The effective rest mass of vector bosons is a decreasing function of the magnetic field intensity. Consequently a diffuse condensation of the bosons appears below a critical value of the field. For typical values of densities and magnetic fields the magnetization is positive and the neutral boson system can maintain a magnetic field self-consistently. A discussion of the relevance in astrophysics is presented.
