Observational Exclusion of a Consistent Quantum Cosmology Scenario
Boris Bolliet, Aurelien Barrau, Julien Grain +1
It is often argued that inflation erases all the information about what took place before it started. Quantum gravity, relevant in the Planck era, seems therefore mostly impossible…
Primordial scalar power spectrum from the Euclidean Big Bounce
Susanne Schander, Aurélien Barrau, Boris Bolliet +3
In effective models of loop quantum cosmology, the holonomy corrections are associated with deformations of space-time symmetries. The most evident manifestation of the deformation…
Phenomenology of bouncing black holes in quantum gravity: a closer look
Aurelien Barrau, Boris Bolliet, Francesca Vidotto +1
It was recently shown that black holes could be bouncing stars as a consequence of quantum gravity. We investigate the astrophysical signals implied by this hypothesis, focusing on…
Comparison of primordial tensor power spectra from the deformed algebra and dressed metric approaches in loop quantum cosmology
B. Bolliet, J. Grain, C. Stahl +2
Loop quantum cosmology tries to capture the main ideas of loop quantum gravity and to apply them to the Universe as a whole. Two main approaches within this framework have been con…
