Abstract:
In the inflationary scenario of loop quantum cosmology (LQC) in the presence
of inverse-volume corrections, we give analytic formulas for the power spectra
of scalar and tensor perturbations convenient to confront with observations.
Since inverse-volume corrections can provide strong contributions to the
running spectral indices, inclusion of terms higher than the second-order
runnings in the power spectra is crucially important. Using the recent data of
cosmic microwave background (CMB) and other cosmological experiments, we place
bounds on the quantum corrections for a quadratic inflaton potential.
