Abstract
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.
期刊介绍：
Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoples’ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
