Abstract

In this research, we have investigated the behavior of massive and massless scalar field (SF) models (normal and phantom) for Kaluza-Klein universe in f(R, T) gravity with cosmological term (Lambda). To obtain field equations, we have used f(R, T) = R + 2h(T) model given by Harko et al. [Phys. Rev. D 84, 024020 (2011)] and anisotropy feature of the universe. Finally, we have discussed our results in f(R, T) and General Relativity Theory (GRT) with various graphics.
