On the cosmological degrees of freedom of Proca field with non-minimal coupling to gravity
Abstract We study Proca theory with non-minimal coupling to gravity through the Ricci tensor and Ricci scalar interactions. We show that in the homogeneous and isotropic Universe together with cosmological constant, the temporal component of the vector field acquires a background value. As a result,...
