Abstract

In this study, we investigated quintessence and tachyon field dark energy (DE) models for the inhomogeneous and anisotropic Ruban universe in f(R,T) gravitation theory. We utilized the Hubble parameter in the field equations as βt+α for the solutions. Since DE candidates are classified according to the pρ values of the EoS parameter ω, we obtained the p and ρ solutions for each DE candidate and analyzed the scalar field (SF) and scalar potential solution. We also talked about the model's physical characteristics and parameters with the help of a various of graphics for redshift z and cosmic time t. Additionally, the statefinder parameters, which are essential tools for distinguishing various dark energy models, have been explored.
