Functional Renormalization for Signal Detection: Dimensional Analysis and Dimensional Phase Transition for Nearly Continuous Spectra Effective Field Theory
Riccardo Finotello, Vincent Lahoche, Dine Ousmane Samary
Signal detection in high dimensions is a critical challenge in data science. While standard methods based on random matrix theory provide sharp detection thresholds for finite-rank…
Time-translation invariance symmetry breaking hidden by finite-scale singularities
Ixandra Achitouv, Vincent Lahoche, Dine Ousmane Samary +1
In this paper, we consider a renormalization group perspective on the quantum dynamics of a particle moving in the Euclidean space through the complex landscape prov…
Renormalization group flow of coupled tensorial group field theories: Towards the Ising model on random lattices
Vincent Lahoche, Dine Ousmane Samary, Antonio D. Pereira
We introduce a new family of tensorial field theories by coupling different fields in a non-trivial way, with a view towards the investigation of the coupling between matter and gr…
Unitary symmetry constraints on tensorial group field theory renormalization group flow
Vincent Lahoche, Dine Ousmane Samary
Renormalization group methods are an essential ingredient in the study of nonperturbative problems of quantum field theory. This paper deal with the symmetry constraints on the ren…
