Linearly Interacting Barrow Holographic Dark Energy in Modified Cosmology

TL;DR

This paper investigates a modified cosmological model with Barrow holographic dark energy, showing that linear interaction is necessary to achieve accelerated expansion and consistent dark energy behavior.

Contribution

It introduces a linear interaction in the BHDE model within modified cosmology to address the lack of acceleration without interaction.

Findings

Linear interaction enables accelerated expansion.

Interaction resolves dark energy equation of state issues.

Thermodynamic consistency is maintained.

Abstract

We study the Barrow holographic dark energy (BHDE) model using the apparent horizon as the infrared (IR) cut-off and ensuring thermodynamic consistency. However, the results show that the BHDE model without any interaction does not yield the accelerated expansion of the universe. Including a linear interaction solves the acceleration and dark energy equation of state parameter problems.
