Functional Dimensional Regularization
Piero Beretta, Alessandro Codello
We introduce and develop Functional Dimensional Regularization (FDR), a novel functional renormalization group (RG) framework that extends the principles of dimensional regularizat…
Exploring multi-parameter optimization in FRG
A. Codello, G. P. Vacca, D. Zarrilli
The use of nonperturbative Wilsonian functional renormalization group (FRG) equations within an unavoidable approximation scheme produces physical results that depend on the choice…
Microscopic dynamics of consensus formation in multi-agent LLM Naming Games
Cristiano De Nobili, Vijayasri Iyer, Alessandro Codello +1
Decentralized populations of Large Language Model (LLM) agents can spontaneously reach consensus on shared conventions, yet the microscopic mechanisms by which their internal stoch…
A universal emulator for planar Ising lattices
Riccardo Ben Alì Zinati, Alessandro Codello
We introduce the notion of an Ising emulator for two-dimensional Ising models: flat, unit-edge-length lattices can be represented as site- or bond-diluted supercells of a single ho…
Classical Renormalization Group Equations for General Relativity
F. Gutiérrez, K. Falls, A. Codello
In a companion paper arXiv:2510.27676, we introduced a non-perturbative classical renormalisation group (RG) flow equation as a novel method for treating strongly interacting probl…
Functional Dimensional Regularization for O(N) Models
P. Beretta, A. Codello
The novel functional dimensional regularization (FDR) scheme has proven capable of yielding results that are competitive with the state-of-the-art in the computation of critical ex…
