Unification of Dark fields and Inflation

We present a partial unified model for inflation, dark matter and dark energy, based on a global SU (2) × U(1) symmetry, where the corresponding cosmological scalar fields that source such components of the Universe appear as different degrees of freedom of fundamental representations. The protectin...

Summary:We present a partial unified model for inflation, dark matter and dark energy, based on a global SU (2) × U(1) symmetry, where the corresponding cosmological scalar fields that source such components of the Universe appear as different degrees of freedom of fundamental representations. The protecting symmetry allows to build successful potentials to describe both the early and late eras of accelerated expansion of the Universe, and admit for the interpretation of Dark energy as quintessence or phantom matter. The model also provides a limit where the fields have a dual behavior.
