# Inflation of universe due to nonlinear electrodynamics

## TL;DR

This paper proposes a nonlinear electrodynamics model where electromagnetic fields drive cosmic inflation, and the resulting predictions align with observational data from PLANCK and WMAP.

## Contribution

It introduces a nonlinear electrodynamics framework with a parameter eta that explains universe inflation driven by magnetic fields, matching observational constraints.

## Key findings

- Universe undergoes inflation driven by nonlinear electromagnetic fields.
- Post-inflation, the universe decelerates towards Minkowski spacetime.
- Predicted spectral index and tensor-to-scalar ratio agree with PLANCK and WMAP data.

## Abstract

A model of nonlinear electrodynamics with a dimensional parameter $\beta$ is considered. Electromagnetic fields are the source of the gravitation field and inflation of the universe. We imply that the universe is filled by stochastic magnetic fields. It is demonstrated that after the universe inflation the universe decelerates approaching the Minkowski spacetime. We evaluate the spectral index, the tensor-to-scalar ratio, and the running of the spectral index which approximately agree with the PLANK and WMAP data.
