Description
Inflation and dark energy share many essential properties. I will describe how these two eras can be easily unified into a common framework based on emergent scale invariance. I will present the associated cosmological history and discuss how the inclusion of non-minimally coupled spectator fields may lead to the spontaneous symmetry breaking of internal symmetries and its eventual restoration at the onset of radiation domination. This sequence of events comes together with a rich phenomenology involving the automatic reheating of the Universe and the generation of short-lived topological defects able to produce an observable gravitational wave background.
