Abstract

We show that the dark energy field can be dynamically obtained at a low scale, e.g. at E=O(eV), via a quantum transitions process. This is achieved if the φ field is coupled with a relativistic scalar field which we call φ. The 2↔2 coupling has a transition rate Γ∝g2T φ and the fields are coupled at low energies when Γ/H≡Tgen/Tφ∝g2/T φ is larger than one, i.e. at T
