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…
Quantum Phase Transitions in the BKL Universe
Giulio D'Odorico, Frank Saueressig
We study quantum corrections to the classical Bianchi I and Bianchi IX universes. The modified dynamics is well-motivated from the asymptotic safety program where the short-distanc…
Covariant computation of effective actions in Horava-Lifshitz gravity
Giulio D'Odorico, Jan-Willem Goossens, Frank Saueressig
We initiate the systematic computation of the heat-kernel coefficients for Laplacian operators obeying anisotropic dispersion relations in curved spacetime. Our results correctly r…
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…
Functional and Local Renormalization Groups
Alessandro Codello, Giulio D'Odorico, Carlo Pagani
We discuss the relation between functional renormalization group (FRG) and local renormalization group (LRG), focussing on the two dimensional case as an example. We show that away…
Scaling and Renormalization in two dimensional Quantum Gravity
Alessandro Codello, Giulio D'Odorico
We study scaling and renormalization in two dimensional quantum gravity in a covariant framework. After reviewing the definition of a proper path integral measure, we use scaling a…
Critical exponents of O(N) models in fractional dimensions
A. Codello, N. Defenu, G. D'Odorico
We compute critical exponents of O(N) models in fractal dimensions between two and four, and for continuos values of the number of field components N, in this way completing the RG…
Asymptotic freedom in Horava-Lifshitz gravity
Giulio D'Odorico, Frank Saueressig, Marrit Schutten
We use the Wetterich equation for foliated spacetimes to study the RG flow of projectable Horava-Lifshitz gravity coupled to n Lifshitz scalars. Using novel results for anisotropic…
A functional RG equation for the c-function
Alessandro Codello, Giulio D'Odorico, Carlo Pagani
After showing how to prove the integrated c-theorem within the functional RG framework based on the effective average action, we derive an exact RG flow equation for Zamolodchikov'…
Consistent closure of renormalization group flow equations in quantum gravity
Alessandro Codello, Giulio D'Odorico, Carlo Pagani
We construct a consistent closure for the beta functions of the cosmological and Newton's constants by evaluating the influence of the fluctuating metric and ghost fields anomalous…
The Renormalization Group and Weyl-invariance
A. Codello, G. D'Odorico, C. Pagani +1
We consider matter fields conformally coupled to a background metric and dilaton and describe in detail a quantization procedure and related renormalization group flow that preserv…
O(N)-Universality Classes and the Mermin-Wagner Theorem
A. Codello, G. D'Odorico
We study how universality classes of O(N)-symmetric models depend continuously on the dimension d and the number of field components N. We observe, from a renormalization group per…
