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…
New universality class in three dimensions: The critical Blume-Capel model
Alessandro Codello, Mahmoud Safari, Gian Paolo Vacca +1
We study the Blume-Capel universality class in dimensions. The RG flow is extracted by looking at poles in fractional dimension of three loop diagrams using $\ov…
Functional perturbative RG and CFT data in the -expansion
Alessandro Codello, Mahmoud Safari, Gian Paolo Vacca +1
We show how the use of standard perturbative RG in dimensional regularization allows for a renormalization group based computation of both the spectrum and a family of coefficients…
Leading CFT constraints on multi-critical models in d>2
Alessandro Codello, Mahmoud Safari, Gian Paolo Vacca +1
We consider the family of renormalizable scalar QFTs with self-interacting potentials of highest monomial below their upper critical dimensions , and st…
