Interacting anisotropic dark energy with hybrid expansion in [formula omitted] gravity

Abstract

This paper investigates the locally rotationally symmetric(LRS) Bianchi type-I cosmological models in f(R,T) gravity, where R is the Ricci scalar and T is the trace of the energy momentum tensor. We find the solutions of the field equations of Bianchi type-I space time by assuming the Hybrid Expansion Law(HEL) for the average scale factor and a particular form of the functional f(R,T)=R+2f(T) where f(T)=μT. It is observed that the Universe with hybrid expansion becomes anisotropic in the early phase, later transforms into isotropic Universe at late epoch. Energy conditions of the model have been investigated. It is observed that strong energy condition is violated which is in agreement with present observation. The derived model also overlaps with ΛCDM at late epoch. We presented both geometrical and physical behaviors of the derived model.
