Anisotropic Universe Models with Perfect Fluid and Scalar Field in f(R,T) Gravity

Understand

In this paper, we study the behavior of perfect fluid and massless scalar field for homogeneous and anisotropic Bianchi type I universe model in $f(R,T)$ gravity, where $R$ is the Ricci scalar and $T$ is the trace of the energy-momentum tensor.

• We assume the variation law of mean Hubble parameter to obtain exact solutions of the modified field equations.
• The physical and kinematical quantities are discussed for both models in future evolution of the universe.
• We check the validity of null energy condition and conclude that our perfect fluid solution can behave like phantom model.
