Barrow agegraphic dark energy

In this work, we propose a new dark energy (DE) model by applying the Barrow entropy and the holographic principle, with a time scale as IR cut-off. Analyzing the conformal time as well as universe's age as infrared cut-offs, we explore the cosmological importance of the suggested DE models and examine the universe evolution filled with the proposed DE applicants and a pressure-less matter. We observe that the equation of state, deceleration, the density parameters can present adequate nature, and these models may also explain the late-time acceleration though the proposed models are unstable except for some values of Barrow exponent Delta. Furthermore, we mention the consequences of the presence of interaction among the universe sectors.

Automated summary

The study introduces a new dark energy model based on Barrow entropy and the holographic principle, using a time scale as an IR cut-off. By analyzing conformal time and the universe's age as infrared cut-offs, the cosmological significance of the suggested DE models is explored. The proposed models exhibit adequate nature in terms of equation of state, deceleration, and density parameters, potentially explaining late-time acceleration.
