- Abstract:
-
We consider the cosmological dynamics of a scalar field in a potential with multiple troughs and peaks. We show that the dynamics of the scalar field will evolve from light dark matter–like behavior (such as that of a light axion) to a combination of heavy dark matter–like and dark energy–like behavior. We discuss the phenomenology of such a model, explaining how it can give rise to the cosmological constant as well as how it can decouple the dark sector densities between the time of recombin...
