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…
The asymptotic speed of reaction fronts in active reaction-diffusion systems
Thibaut Demaerel, Christian Maes
We study various combinations of active diffusion with branching, as an extension of standard reaction-diffusion processes. We concentrate on the selection of the asymptotic wavefr…
Death and resurrection of a current by disorder, interaction or activity
Thibaut Demaerel, Christian Maes
Because of disorder the current-field characteristic may show a first order phase transition as function of the field, at which the current jumps to zero when the driving exceeds a…
Active processes in one dimension
Thibaut Demaerel, Christian Maes
We consider the thermal and athermal overdamped motion of particles in 1D geometries where discrete internal degrees of freedom (spin) are coupled with the translational motion. Ad…
Stabilization in the eye of a cyclone
Thibaut Demaerel, Christian Maes, Karel Netočný
We consider the systematic force on a heavy probe induced by interaction with an overdamped diffusive medium where particles undergo a rotating force around a fixed center. The sti…
