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…

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…

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…
