Quantum Gravity from Fundamental Questions to Phenomenological Applications
Natalia Alkofer
Investigating quantum gravity requires a comprehension of both, general relativity and quantum field theory. Therefore this thesis starts, after a general introduction to the treat…
Renormalisation Group for Gravity and Dimensional Reduction
Natalia Alkofer
The functional renormalisation group for the Einstein-Hilbert action is investigated for the case of four infinite (or large) and one compact dimension. The motivation for this stu…
Asymptotically Safe -Gravity Coupled to Matter II: Global Solutions
Natalia Alkofer
Ultraviolet fixed point functions of the functional renormalisation group equation for -gravity coupled to matter fields are discussed. The metric is split via the exponentia…
Asymptotically safe f(R)-gravity coupled to matter I: the polynomial case
Natalia Alkofer, Frank Saueressig
We use the functional renormalization group equation for the effective average action to study the non-Gaussian renormalization group fixed points (NGFPs) arising within the framew…
Quantum Gravity signatures in the Unruh effect
Natalia Alkofer, Giulio D'Odorico, Frank Saueressig +1
We study quantum gravity signatures emerging from phenomenologically motivated multiscale models, spectral actions, and Causal Set Theory within the detector approach to the Unruh…
Black holes in Asymptotically Safe Gravity
Frank Saueressig, Natalia Alkofer, Giulio D'Odorico +1
Black holes are among the most fascinating objects populating our universe. Their characteristic features, encompassing spacetime singularities, event horizons, and black hole ther…
Spectral dimensions from the spectral action
Natalia Alkofer, Frank Saueressig, Omar Zanusso
The generalised spectral dimension provides a powerful tool for comparing different approaches to quantum gravity. In this work, we apply this formalism to the classica…
The non-perturbative BRST quartet mechanism in Landau gauge QCD: Ghost-gluon and ghost-quark bound states
Natalia Alkofer, Reinhard Alkofer
The non-perturbative BRST quartet mechanism in infrared Landau gauge QCD is presented. It is demonstrated that positivity violation for transverse gluons allows to identify the glu…
Ghost-gluon and ghost-quark bound states and their role in BRST quartets
Natalia Alkofer, Reinhard Alkofer
A non-perturbative version of the BRST quartet mechanism in infrared Landau gauge QCD is proposed for transverse gluons and quarks. Based on the positivity violation for transverse…
The non-perturbative BRST quartets generated by transverse gluons or quarks in Landau gauge
Natalia Alkofer, Reinhard Alkofer
The BRST quartet mechanism is briefly reviewed. A special emphasis is given to the distinction of perturbative versus non-perturbative quartets. The field contents of the non-pertu…
Features of ghost-gluon and ghost-quark bound states related to BRST quartets
Natalia Alkofer, Reinhard Alkofer
The BRST quartet mechanism in infrared Landau gauge QCD is investigated. Based on the observed positivity violation for transverse gluons the field content of th…
