Consistent Cosmic Microwave Background Spectra from Quantum Depletion
  Following a new quantum cosmological model proposed by Dvali and Gomez, we
quantitatively investigate possible modifications to the Hubble parameter and
following corrections to the cosmic microwave background spectrum. In this
model, scalar and tensor perturbations are generated by the quantum depletion
of the background inflaton and graviton condensate respectively. We show how
the inflaton mass affects the power spectra and the tensor-to-scalar ratio.
Masses approaching the Planck scale would lead to strong deviations, while
standard spectra are recovered for an inflaton mass much smaller than the
Planck mass.
