Matter non-conservation in the universe and dynamical dark energy
In an expanding universe, the vacuum energy density ρ Λ is expected to be a dynamical quantity. In quantum field theory in curved spacetime, ρ Λ should exhibit a slow evolution, determined by the expansion rate of the universe H. Recent measurements on the time variation of the fine-structure consta...
