Abstract EN
This paper is devoted to study the cosmological behavior of homogeneous and isotropic universe model in the context of f(R,Tφ) gravity, where φ is the scalar field.
For this purpose, we follow the first-order formalism defined by H=W(φ).
We evaluate Hubble parameter, effective equation of state parameter (ωeff), deceleration parameter, and potential of scalar field for three different values of W(φ).
We obtain phantom era in some cases for the early times.
It is found that exponential expression of W(φ) yields ωeff independent of time for flat universe and independent of model parameter otherwise.
It is concluded that our model corresponds to ΛCDM for both initial and late times.
