Abstract

© 2021 Elsevier B.V.Non-static Einstein–Rosen universe with scalar field is examined via two different selection of f(R,T) models. Firstly, we analyzed Einstein–Rosen universe with scalar field in f(R,T)=R+2f(T) model. Then, we constructed field equations for f(R,T)=f1(R)+f2(R)f3(T) model, as well. For both models, exact solutions of field equations have been attained without considering any approximation or restriction. Whether scalar field corresponds to phantom and/or quintessence scalar field are investigated for each models.
