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…
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…
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'…
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…
