Elimination of cosmological singularities in quantum cosmology by suitable operator orderings
Thibaut Demaerel, Ward Struyve
Canonical quantization of general relativity does not yield a unique quantum theory for gravity. This is in part due to operator ordering ambiguities. In this paper, we investigate…
Producing suprathermal tails in the stationary velocity distribution
Thibaut Demaerel, Wojciech De Roeck, Christian Maes
We revisit effective scenarios for the origin of heavy tails in stationary velocity distributions. A first analysis combines localization with diffusive acceleration. That gets rea…
Cosmic acceleration from quantum Friedmann equations
Thibaut Demaerel, Christian Maes, Ward Struyve
We consider a simplified model of quantum gravity using a mini-superspace description of an isotropic and homogeneous universe with dust. We derive the corresponding Friedmann equa…
