Impact of generalized holonomy corrections on the cosmological primordial power spectra
arXiv:2212.01182 · doi:10.1103/PhysRevD.107.126008
Abstract
The propagation of perturbations is studied with generalized holonomy corrections in a fully consistent way, ensuring that the deformed algebra of constraints remains closed. The primordial cosmological power spectra are calculated. It is shown that, although the detailed form of the correction does unavoidably impact the observables, the main known results of loop quantum cosmology are robust in this respect.
