Universality of free fall in Planck-scale deformed Newtonian gravity
Giuseppe Fabiano, Domenico Frattulillo, Christian Pfeifer +1
The universality of free fall is one of the most cherished principles in classical gravity. Its fate in the quantum world is one of the key questions in fundamental physics. We inv…
Regulator and gauge dependence of the Abelian gauge coupling in asymptotically safe quantum gravity
Maksym Riabokon, Marc Schiffer, Fabian Wagner
Both General Relativity and the Standard Model of particle physics are not UV complete. General Relativity is perturbatively non-renormalizable, while the Standard Model features L…
Spin couplings as witnesses of Planck scale phenomenology
Pasquale Bosso, Fabrizio Illuminati, Luciano Petruzziello +1
Modified dispersion relations (MDRs) and noncommutative geometries are phenomenological models of Planck-scale corrections to relativistic kinematics, motivated by several approach…
Weak equivalence principle and nonrelativistic limit of general dispersion relations
Manuel Hohmann, Christian Pfeifer, Fabian Wagner
We study the weak equivalence principle in the context of modified dispersion relations, a prevalent approach to quantum gravity phenomenology. We find that generic modified disper…
