# Cosmological comoving behavior of the configurational entropy

## TL;DR

This paper investigates how the configurational entropy (CE) evolves in a flat FRW universe, showing specific scaling behaviors for different cosmic components and suggesting CE's potential as a theoretical tool for understanding large-scale cosmic interactions.

## Contribution

It demonstrates the cosmological comoving behavior of the CE density and its dependence on the scale factor for various cosmic constituents, extending the understanding of CE in cosmology.

## Key findings

- CE density scales as a^{-3} for radiation
- CE density scales as a^{-3/2} for non-relativistic matter
- Results applicable to matter, radiation, and ΛCDM cosmology

## Abstract

It has been shown that a functional dependence of the configurational entropy (CE) density exhibits a cosmological comoving behavior related to the scale parameter, $a$, of the FRW flat universe. Such a circumstantial comoving behavior shows that the CE evolves with $a^{-3}$ for fermionic and bosonic radiation and with $a^{-3/2}$ for non-relativistic fermionic matter. The results are discussed in the domain of matter and radiation, as well as in a simplified context of the $\Lambda$CDM cosmology. Our results suggest that the CE can work as a theoretical driver for particle and nuclear interactions in the context of large scale cosmic events.
