Cosmological application of the Maxwell gravity

Abstract: In this study, we consider a cosmological model for the Maxwell gravity which is constructed by gauging the semi-simple extended Poincar\'e algebra. Inspired by the Einstein-Yang-Mills theory, we describe the Maxwell gauge field in terms of two additional time-dependent scalar fields. Within the context of a homogeneous and isotropic Friedmann-Lema^itre-Robertson-Walker universe, we derive the Friedmann equations together with new contributions. Additionally, we find the exact expressions for the additional scalar fields, considering the exponential evolution of the scale factor. Moreover, we investigate the gauge theory of gravity based on the Maxwell algebra and demonstrate that this model leads to the (anti) de Sitter universe as well as a non-accelerated universe model.
