Impact of generalized holonomy corrections on the cosmological primordial power spectra
Maxime De Sousa, Killian Martineau, Cyril Renevey +1
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 p…
Detailed analysis of the curvature bounce: background dynamics and imprints in the CMB
Cyril Renevey, Aurélien Barrau, Killian Martineau
If the spatial sections of the Universe are positively curved, extrapolating the inflationary stage backward in time inevitably leads to a classical bounce. This simple scenario, n…
Catastrophic fate of Schwarzschild black holes in a thermal bath
Aurélien Barrau, Killian Martineau, Cyril Renevey
Using the Schwarzschild metric as a rudimentary toy model, we pedagogically revisit the curious prediction that the mass of a classical black hole in a constant temperature thermal…
The holographic space-time and black hole remnants as dark matter
Aurélien Barrau
The holographic space-time approach to inflation provides a well defined and self-contained framework to study the early universe. Based on a quasi-local quantum gravity theory gen…
