Scalar spectra of primordial perturbations in loop quantum cosmology
  This article is devoted to the study of scalar perturbations in loop quantum
cosmology. It aims at clarifying the situation with respect to the way initial
conditions are set and to the specific choice of an inflaton potential. Several
monomial potentials are studied. Both the dressed metric and deformed algebra
approaches are considered. We show that the calculation of the ultraviolet part
of the spectrum, which is the physically relevant region for most background
trajectories, is reliable, whereas the infrared and intermediate parts do
depend on some specific choices that are made explicit.
