Saez-Ballester gravity in Kantowski-Sachs Universe: a new reconstruction paradigm for Barrow Holographic Dark Energy

Understand

We reconstruct Barrow Holographic Dark Energy (BHDE) within the framework of Saez-Ballester Scalar Tensor Theory.

• As a specific background, we consider a homogeneous and anisotropic Kantowski-Sachs Universe filled up with BHDE and dark matter.
• By assuming the Hubble radius as an IR cutoff, we investigate both the cases of non-interacting and interacting dark energy scenarios.
• We analyze the evolutionary behavior of various model parameters, such as skewness parameter, Equation-of-State parameter, deceleration parameter, jerk parameter and squared sound speed.
