Abstract

In this work, we analyze the properties of wormhole solutions in modified gravitational theory, i.e., f(R,T), where R denotes the Ricci scalar and T represents the trace of the energy-momentum tensor. We develop wormhole models by employing holographic dark energy density profiles inspired by Rényi, Moradpour and Bekenstein-Hawking, expressed respectively as: ρ_R=α4α₁r⁴c²κln(1+πα₁r²),ρ_M=α4πr²c²κ(πα₁r²+1),ρ_BH=α4c²κr², where α and β are dimensional parameters of units L⁻². The derived shape functions satisfy the necessary conditions for traversable wormholes. We examine the influence of parameters α and β on the equilibrium state and violation of energy conditions. Our analysis reveals that the null-energy condition (NEC) is not satisfied, thereby indicating the necessary of exotic matter. Geometric features are further explored through embedding diagrams.
