Scalar Fields for Bianchi-I Model in $\boldsymbol{f(R,T)}$ Theory of Gravity

In physics and cosmology, scalar fields are considered basic. In this study, we are interested to inspect the conduct of massless scalar field (SF) and massive scalar field (MSF) models in \(f(R,T)\) theory for Bianchi-I universe models. We discuss two cosmological models with respect to late cosmic acceleration, using constant scalar potential and exponential scalar potential models. Also, we study the behavior of a massive scalar field. Finally, we obtain our results in \(f(R,T)\) and general relativity (GR). In addition, we obtained an LRS Bianchi-I metric as a result of the solutions we made and selection of special constants.
