The fate of multi-critical universal behaviour
Nicolò Defenu, Alessandro Codello
The multi-critical fixed points of symmetric models cease to exist in the limit, but the mechanism regulating their annihilation still presents several enigmati…

Scaling solutions in the derivative expansion
N. Defenu, A. Codello
Scalar field theories with -symmetry are the traditional playground of critical phenomena. In this work these models are studied using functional renormalization gr…

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…
