Description
In this talk we explore the possibility of describing an interacting dark sector as result of breaking the invariance under diffeomorphism of the matter action. Particularly, we consider two scalar fields with different non-canonical minimal couplings to gravity. We consider the potential and kinetic domination regimes for each field and analyze the resulting models. Then, we focus on cases describing dark matter-dark energy interaction and compare its predictions to observations.
