Primordial tensor power spectrum in holonomy corrected Omega-LQC
Linda Linsefors, Thomas Cailleteau, Aurelien Barrau +1
The holonomy correction is one of the main terms arising when implementing loop quantum gravity ideas at an effective level in cosmology. The recent construction of an anomaly free…
Consistency of holonomy-corrected scalar, vector and tensor perturbations in Loop Quantum Cosmology
Thomas Cailleteau, Aurelien Barrau, Julien Grain +1
Loop Quantum Cosmology yields two kinds of quantum corrections to the effective equations of motion for cosmological perturbations. Here we focus on the holonomy kind and we study…
Quantum gravity in the sky
Aurelien Barrau, Julien Grain
Quantum gravity is known to be mostly a kind of metaphysical speculation. In this brief essay, we try to argue that, although still extremely difficult to reach, observational sign…
