HOW TO OBTAIN DARK ENERGY AT LOW ENERGY (LATE TIME)
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 completely 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.
