Title: The Power Spectrum in Quantum Inflationary Cosmology
Abstract: We analyze fluctuations of a generic scalar field around its vacuum state in a singularity free quantum cosmology. We follow the evolution of the scalar field fluctuations in the subhorizon and superhorizon regime on a spacetime close to de Sitter spacetime, with quantum corrections to the classical geometry taken into account in the mean field approach. In this framework we calculate the power spectrum and discuss its leading imprint from a quantum inflationary stage.
