The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

Quantum geometry predicts that a universe evolves through an inflationary phase at small volume before exiting gracefully into a standard Friedmann phase. This does not require the introduction of additional matter fields with ad hoc potentials; rather, it occurs because of a quantum gravity modification of the kinetic part of ordinary matter Hamiltonians. An application of the same mechanism can explain why the present-day cosmological acceleration is so tiny.

The paper

Original abstract

Quantum geometry predicts that a universe evolves through an inflationary phase at small volume before exiting gracefully into a standard Friedmann phase. This does not require the introduction of additional matter fields with ad hoc potentials; rather, it occurs because of a quantum gravity modification of the kinetic part of ordinary matter Hamiltonians. An application of the same mechanism can explain why the present-day cosmological acceleration is so tiny.

Quantum Nature of the Big Bang: An Analytical and Numerical Investigation
gr-qc 2006-04 conditional novelty 7.0 of 10

In loop quantum cosmology, a flat homogeneous universe with a massless scalar field replaces the big-bang singularity with a deterministic quantum bounce connecting contraction and expansion.
Deformed General Relativity and Effective Actions from Loop Quantum Gravity

Reconstructing effective actions from deformed constraint algebras shows that loop quantum gravity's inverse-triad corrections reshape the action at second order, and that holonomy corrections turn the high-density re...
Observational test of inflation in loop quantum cosmology
gr-qc 2011-07 conditional novelty 6.0 of 10

Inverse-volume corrections from loop quantum cosmology enhance large-scale power; fitting them to WMAP7 plus other data bounds the correction amplitude and leaves a quartic inflaton potential in tension.
Quasinormal modes of a rotating loop quantum black hole

Quasinormal modes of a massless scalar field on a rotating loop quantum black hole background exhibit reduced real frequencies and damping rates with increasing quantum corrections, with rotation introducing crossover...
The Scale Factor Potential Approach to Inflation
gr-qc 2019-09 reject novelty 3.0 of 10

The paper reparametrizes slow-roll inflation through a scale factor potential and constructs an example potential, but the chosen 60 e-fold branch is inconsistent with its own first-minimum end condition.

This is so called the super-inflationary scenario [ref] and is a result of the quantum nature of spacetime in the Planck scales.

Though the issue of super-inflation in LQC has been discussed widely in the literature (see, e.g., [ref] ), we still make some analyses here for maintaining this paper self-contained.
