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…
Functional renormalization group for p=2 like glassy matrices in the planar approximation: I. Vertex expansion at equilibrium
Vincent Lahoche, Dine Ousmane Samary
In this paper, we study the equilibrium states of a stochastic complex random matrix , whose entries evolve in time accordingly with a Langevin equation including bo…
Functional renormalization group for multilinear disordered Langevin dynamics II: Revisiting the spin dynamics for Wigner and Wishart ensembles
Vincent Lahoche, Dine Ousmane Samary, Mohamed Tamaazousti
In this paper, we investigate the large-time behavior for a slightly modified version of the standard p=2 soft spins dynamics model, including a quartic or higher potential. The eq…
Functional Renormalization Group Approach for Signal Detection
Vincent Lahoche, Dine Ousmane Samary, Mohamed Tamaazousti
This review paper uses renormalization group techniques for signal detection in nearly-continuous positive spectra. We highlight universal aspects of the analogue field-theory appr…
Functional renormalization group for multilinear disordered Langevin dynamics I: Formalism and first numerical investigations at equilibrium
Vincent Lahoche, Dine Ousmane Samary, Mohamed Ouerfelli
This paper aims at using the functional renormalization group formalism to study the equilibrium states of a stochastic process described by a quench--disordered multilinear Langev…
Field theoretical approach for signal detection in nearly continuous positive spectra I: Matricial data
Vincent Lahoche, Dine Ousmane Samary, Mohamed Tamaazousti
Renormalization group techniques are widely used in modern physics to describe the low energy relevant aspects of systems involving a large number of degrees of freedom. Those tech…
Reliability of the local truncations for the random tensor models renormalization group flow
Vincent Lahoche, Dine Ousmane Samary
The standard nonperturbative approaches of renormalization group for tensor models are generally focused on a purely local potential approximation (i.e. involving only generalized…
Flowing in discrete gravity models and Ward identities: A review
Ezinvi Baloitcha, Vincent Lahoche, Dine Ousmane Samary
Ward-Takahashi identities are nonperturbative relations between correlation functions and arising from symmetries in quantum and statistical fields theories, as Noether currents co…
Pedagogical comments about nonperturbative Ward-constrained melonic renormalization group flow
Vincent Lahoche, Dine Ousmane Samary
This paper, in addition to our recent works, intends to explore the behavior of the Wetterich flow equations in the portion of the theory space spanned by non-branching melons cons…
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…
Revisited functional renormalization group approach for random matrices in the large- limit
Vincent Lahoche, Dine Ousmane Samary
The nonperturbative renormalization group has been considered as a solid framework to investigate fixed point and critical exponents for matrix and tensor models, expected to corre…
Nonperturbative renormalization group beyond melonic sector: The Effective Vertex Expansion method for group fields theories
Vincent Lahoche, Dine Ousmane Samary
Tensor models admit the large limit, dominated by the graphs called melons. The melons are characterized by the Gurau number and the amplitude of the Feynman graphs…
