Vacuum energy reduction through destabilization: a unification of quintessence and a dynamical approach?

For example, an extremely slowly varying and light scalar field that rolls toward the vanishing vacuum energy state is needed, which must satisfy the required initial conditions so that the energy density in matter is comparable to the energy density stored in quintes...
