Anisotropic Long-Range Spin Systems
Nicolò Defenu, Andrea Trombettoni, Stefano Ruffo
We consider anisotropic long-range interacting spin systems in dimensions. The interaction between the spins decays with the distance as a power law with different exponents in…

Truncation Effects in the Functional Renormalization Group Study of Spontaneous Symmetry Breaking
N. Defenu, P. Mati, I. G. Marian +2
We study the occurrence of spontaneous symmetry breaking (SSB) for O(N) models using functional renormalization group techniques. We show that even the local potential approximatio…

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…
