Editorial: Coarse graining in quantum gravity -- Bridging the gap between microscopic models and spacetime physics
Astrid Eichhorn, Benjamin Bahr, Antonio D. Pereira
The Renormalization Group encodes three concepts that could be key to accelerate progress in quantum gravity. First, it provides a micro-macro connection that could connect microsc…
The Higgs Mass and the Scale of New Physics
Astrid Eichhorn, Holger Gies, Joerg Jaeckel +3
In view of the measured Higgs mass of 125 GeV, the perturbative renormalization group evolution of the Standard Model suggests that our Higgs vacuum might not be stable. We connect…
The Renormalization Group flow of unimodular f(R) gravity
Astrid Eichhorn
Unimodular gravity is classically equivalent to General Relativity. This equivalence extends to actions which are functions of the curvature scalar. At the quantum level, the dynam…
Towards phase transitions between discrete and continuum quantum spacetime from the Renormalization Group
Astrid Eichhorn, Tim Koslowski
We establish the functional Renormalization Group as an exploratory tool to investigate a possible phase transition between a pre-geometric discrete phase and a geometric continuum…
Stability of fixed points and generalized critical behavior in multifield models
Astrid Eichhorn, David Mesterházy, Michael M. Scherer
We study models with three coupled vector fields characterized by symmetry. Using the nonperturbative functional renormalization group, we deriv…
The Planck scale, the Higgs mass and scalar dark matter
Astrid Eichhorn, Michael M. Scherer
This study is inspired by a scenario, in which the Standard Model, enhanced by an additional dark matter scalar, could be extended up to the Planck scale, while accommodating the l…
