Creating perturbations from a decaying field during inflation
  Typically the fluctuations generated from a decaying field during inflation
do not contribute to the large scale structures. In this paper we provide an
example where it is possible for a field which slowly rolls and then decays
during inflation to create all the matter perturbations with a slightly
red-tilted spectral index, with no isocurvature perturbations, and with a
possibility of a departure from Gaussian fluctuations.
