Assuming dark energy de-coherence occurs during early times when the scale parameter expansion rate is no longer supra-luminal specifies a class of cosmological models in which the cosmic microwave background fluctuation amplitude at last scattering is approximately $10^{-5}$.9 pages, 1 figureAstrophysicsCosmic Microwave Background Fluctuation Amplitude from Dark Energy De-Coherencetext
