Renormalization group flows and fixed points for a scalar field in curved space with nonminimal coupling
Boris S. Merzlikin, Ilya L. Shapiro, Andreas Wipf +1
Using covariant methods, we construct and explore the Wetterich equation for a non-minimal coupling of a quantized scalar field to the Ricci scalar of a prescribed curved s…
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…
A functional perspective on emergent supersymmetry
Holger Gies, Tobias Hellwig, Andreas Wipf +1
We investigate the emergence of supersymmetry in the long-range behavior of three-dimensional parity-symmetric Yukawa systems. We discuss a renormalization approach th…
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…
