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…
