TL;DR: Using techniques from loop quantum gravity, the standard inflationary paradigm is extended to a self-consistent theory from the Planck scale to the onset of slow roll inflation, covering some 11 orders of magnitude in energy density and curvature.

TL;DR: In this paper, a self consistent extension of the inflationary paradigm over the 11 orders of magnitude in density and curvature, from the big bounce to the onset of slow roll, is presented.

TL;DR: In this article, the standard theory of cosmological perturbations is extended to overcome this limitation by distinguishing between the true and apparent trans-Planckian difficulties and providing sufficient conditions under which the true difficulties can be overcome within a quantum gravity theory.

TL;DR: In this paper, the perturbations arising from gravitationally induced stimulated creation were computed for a general statistical density operator that describes an initial mixed state that includes probabilities for nonzero numbers of scalar perturbation to be present at early times during inflation and showed that the initial presence of quanta can significantly enhance non-Gaussianities in the so-called squeezed limit.
