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…
Renormalisation Group approach to General Relativity
F. Gutiérrez, K. Falls, A. Codello
The detection of gravitational waves has intensified the need for efficient, high-precision modeling of the two-body problem in General Relativity. Current analytical methods, prim…
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…
Rethinking Dimensional Regularization in Critical Phenomena
P. Beretta, A. Codello
We show that it is possible to use dimensional regularization (DR) beyond the usual -expansion in the context of renormalization group (RG) calculations in Critical Ph…
