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.
