# Possible observational effects of loop quantum cosmology

@article{Mielczarek2009PossibleOE, title={Possible observational effects of loop quantum cosmology}, author={Jakub Mielczarek}, journal={Physical Review D}, year={2009}, volume={81}, pages={063503} }

In this paper, we consider realistic model of inflation embedded in the framework of loop quantum cosmology. Phase of inflation is preceded here by the phase of a quantum bounce. We show how parameters of inflation depend on the initial conditions established in the contracting, prebounce phase. Our investigations indicate that phase of the bounce easily sets proper initial conditions for the inflation. Subsequently, we study observational effects that might arise due to the quantum…
