Behaviors of dark energy candidates in the Ruban universe

OpenAlex İngilizce

In this study, we investigated quintessence and tachyon field dark energy (DE) models for the inhomogeneous and anisotropic Ruban universe in [Formula: see text] gravitation theory. We utilized the Hubble parameter in the field equations as [Formula: see text] for the solutions. Since DE candidates are classified according to the [Formula: see text] values of the EoS parameter [Formula: see text], we obtained the p and [Formula: see text] 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.
