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…

Large time effective kinetics -functions for quantum (2 + p)-spin glass II: Effective vertex expansion, local potential approximation and symmetries

Bêm-Biéri Barthélémy Natta, Vincent Lahoche, Dine Ousmane Samary +1

This paper aims to study the functional renormalization group for quantum -spin dynamics of a -vector . By fixing the gauge symmetry in the co…

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…

Large time effective kinetics -functions for quantum (2+p)-spin glass

Vincent Lahoche, Dine Ousmane Samary, Parham Radpay

This paper examines the quantum -spin dynamics of a -vector through the lens of renormalization group (RG) theory. The RG is based on a coars…

On the injective norm of random fermionic states and skew-symmetric tensors

Stephane Dartois, Parham Radpay

We study the injective norm of random skew-symmetric tensors and the associated fermionic quantum states, a natural measure of multipartite entanglement for systems of indistinguis…

Constructing the low-temperature phase diagram for the -quantum spin glass using the nonperturbative renormalization group

Ixandra Achitouv, Vincent Lahoche, Dine Ousmane Samary +1

In this paper, we use a nonperturbative renormalization group approach to construct the dynamical phase space of a quantum spin glass in the large limit. The disordered Hamilto…
