Generalized ModMax and the Early Universe

TL;DR

This paper explores a cosmological model based on Generalized ModMax nonlinear electrodynamics, demonstrating its potential to avoid initial singularities and produce an inflationary epoch consistent with current observational parameters.

Contribution

It introduces a novel cosmological model using Generalized ModMax electrodynamics that can generate a non-singular universe with a realistic inflationary phase.

Findings

The model can avoid the initial singularity with suitable parameters.

It produces an inflationary epoch consistent with current observational data.

The universe's evolution aligns with observed values of $N$, $n_s$, and $r$.

Abstract

In this work, we study a cosmological model driven by Generalized ModMax nonlinear electrodynamics. We find that, with an appropriate choice of the theory's parameters, the universe's initial singularity can be avoided. Moreover, we also find that this model has an inflationary epoch that is consistent with the current values for $N$, $n_s$ and $r$. Therefore, using Generalized ModMax, we can construct a non singular Universe with an inflationary epoch.
