Description

Motivated by the great interest in holographic dark energy models, this study reconstructs Barrow Holographic Dark Energy (BHDE) within the Saez Ballester framework in a homogeneous and anisotropic Kantowski Sachs universe. Interacting and non-interacting scenarios are considered, with the future event horizon serving as the infrared cut-off. Our analysis examines the evolution of the Equation of State parameter and the phase space trajectories for both cases. The inflationary dynamics of a universe filled with BHDE are further explored by plotting the slow roll parameters. Additionally, we establish a connection between BHDE and the canonical scalar field, which is often linked to inflationary processes. Finally, the tensor to scalar ratio is plotted and found to lie within the acceptable range.
