Abstract
In this study, normal, phantom scalar fields (SF) and massive scalar field (MSF) solutions were investigated in f(R, T) and General Relativity theories (GRT) for inhomogeneous and anisotropic Ruban space-time, which is believed to represent the first moments of the universe. Solutions were obtained by using the \(A(x,t)=(x B(t))^n\) relation between the metric potentials of the Ruban universe and the scalar potential models \(V(\phi )=V_0\) and \(V(\phi )=V_0 e^{-\alpha \phi (t)}\). Obtained results are supported by graphics. The solutions obtained for scalar fields are compatible with the studies of Aygün (Gravit Cosmol 24:302–307, 2018) and Singh and Singh (Astrophys Space Sci 356:153–162, 2015).
