Effects of Electromagnetic Field on the Dynamics of Bianchi type $VI_0$ Universe with Anisotropic Dark Energy

TL;DR

This paper investigates how electromagnetic fields influence the anisotropic evolution of Bianchi type VI_0 universe models with dark energy, showing electromagnetic fields promote anisotropy that diminishes over time, leading to an isotropic universe.

Contribution

It provides exact solutions to Einstein's equations for anisotropic cosmological models with electromagnetic fields and dark energy, highlighting the electromagnetic field's role in anisotropy evolution.

Findings

Electromagnetic field enhances anisotropic behavior initially.

Dark energy becomes isotropic in the future despite electromagnetic influence.

Universe models tend toward isotropy over time.

Abstract

Spatially homogeneous and anisotropic Bianchi type $VI_0$ cosmological models with cosmological constant are investigated in the presence of anisotropic dark energy. We examine the effects of electromagnetic field on the dynamics of the universe and anisotropic behavior of dark energy. The law of variation of the mean Hubble parameter is used to find exact solutions of the Einstein field equations. We find that electromagnetic field promotes anisotropic behavior of dark energy which becomes isotropic for future evolution. It is concluded that the isotropic behavior of the universe model is seen even in the presence of electromagnetic field and anisotropic fluid.
