A Model with Quadratic Equation of State in f (R, T) Theory

Abstract

In this paper we have studied Bianchi type-I cosmological model with quadratic equation  of state in f (R, T) theory of gravity proposed by Harko et al. (Phys. Rev. D 84:024020, 2011). For a specific choice of   f (R, T) = R + 2f(T) where f(T) = - λT. We have discussed two cases of f (R, T) gravity, i.e., (i) f (R, T) = R + 2f(T); (ii) f (R, T) = f₁(R) + f₂(R) for both the cases we obtain that universe starts with a big-bang at initial time and both become isotropic at late times. Also we obtain  models are accelerating.
