Power-Law Cosmic Expansion in f(R) Gravity for Kaluza-Klein Metric

Abstract

Taking into account the f(R) gravity framework in our study, we investigated the Tsallis Holographic Dark Energy (THDE)  model utilizing Hubble's Horizon as the infrared (IR) cut-off in Kaluza-Klein metric. We assume a relation Fαa^n and volumetric power law expansion to solve the field equations (where n remains unchanged).The resulting model's kinematical and physical characteristics are examined via graphical representation. The corresponding values expected for cosmic expansion are included in the graphical analysis of the equation of state parameter.
