We present a new mechanism that allows to unify inflation and dark energy. We use a scalar field φ with a potential ν(φ) that has two at regions at high and low energies that are associated with inflation and dark energy respectively. After inflation φ decays com- pletely and reheat the universe. Eventually φ is regenerated at late times close to present via a quantum process and the dark energy epoch begins. The φ particles production starts at low energies and this explains the cosmological coincidence problem. Copyright © 2012 by World Scientific Publishing Co. Pte. Ltd.

Abstract

We present a new mechanism that allows to unify inflation and dark energy. We use a scalar field φ with a potential ν(φ) that has two at regions at high and low energies that are associated with inflation and dark energy respectively. After inflation φ decays com- pletely and reheat the universe. Eventually φ is regenerated at late times close to present via a quantum process and the dark energy epoch begins. The φ particles production starts at low energies and this explains the cosmological coincidence problem. Copyright © 2012 by World Scientific Publishing Co. Pte. Ltd.
