In this paper, locally rotationally symmetric Bianchi type-I cosmological models in f(R,ϕ) theory of gravity have been investigated, where R and ϕ are Ricci scalar and scalar potential function, respectively. Some exact solutions pertaining to the dark energy and the cosmic expansion have been found by implementing the power law model f(R,ϕ)=λRm+1+βϕl+1, with λ, m, β and l being the arbitrary real constants, such that m,β≠−1 for the sake of...
