Relational background field formulation of discrete quantum gravity models: The case of vector models in zero dimensions
Vincent Lahoche, Dine Ousmane Samary, Parham Radpay
In a recent paper arxiv.org/abs/2609.21031, we have introduced the concept of a relational background field as a new approach to the renormalization group (RG) for discrete quantum…
Inferring the microscopic mechanisms of opinion dynamics using a kinetic Ising model
Ixandra Achitouv, David Chavalarias, Vincent Lahoche
Kinetic Ising models are widely used to describe binary opinion dynamics, but their microscopic validity has rarely been tested empirically. Here, we infer the transition probabili…
Functional Renormalization for Random Matrix Theory: The relational background field method
Vincent Lahoche, Dine Ousmane Samary
The construction of a reliable renormalization group (RG) flow for discrete gravity models that preserves their underlying symmetry group, typically or , remains an op…
Data Field Theory: Theory and Applications of the Functional Renormalization Group for Signal Detection
Riccardo Finotello, Vincent Lahoche, Dine Ousmane Samary +1
We review the renormalization group framework for signal detection in high-dimensional data, tailored to the regime where the signal may be of extensive rank and does not separate…
Field Theory of Data: Anomaly Detection via the Functional Renormalization Group. The 2D Ising Model as a Benchmark
Riccardo Finotello, Vincent Lahoche, Parham Radpay +1
We establish a correspondence between anomaly detection in high-noise regimes and the renormalization group flow of non-equilibrium field theories. We provide a physical grounding…
Functional Renormalization Group for a Rank-4 Renormalizable Tensorial Group Field Theory with Derivative Necklace Couplings
Seke Fawaaz Zime Yerima, Vincent Lahoche, Dine Ousmane Samary
We apply the functional renormalization group to an Abelian Group Field Theory extended beyond the branched-polymer (melonic) sector by including interactions that are subdominant…
