The quantum -spin renormalization group in the large limit as a benchmark for functional renormalization group
Vincent Lahoche, Dine Ousmane Samary, Parham Radpay
To gain a deeper understanding of the glassy phase in -spin quantum models, this paper examines the dynamics of the -vector through the framework of…
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…
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…
Signal inference in financial stock return correlations through phase-ordering kinetics in the quenched regime
Ixandra Achitouv, Vincent Lahoche, Dine Ousmane Samary
Financial stock return correlations have been analyzed through the lens of random matrix theory to differentiate the underlying signal from spurious correlations. The continuous sp…
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…
Functional renormalization group for p=2 like glassy matrices in the planar approximation: III. Equilibrium dynamics and beyond
Vincent Lahoche, Dine Ousmane Samary
This paper is the last of the series investigating renormalization group aspects of stochastic random matrices, including a Wigner-like disorder. We consider the equilibrium dynami…
An intriguing connection between Pisarski's fixed point and (2+3)-spin glasses
Vincent Lahoche, Dine Ousmane Samary
This paper aims to establish a connection between Pisarski's fixed point and a (2+3)-spin-glass model with sextic confinement potential. This is made possible by the unconventional…
Functional renormalization group for like glassy matrices in the planar approximation: II. Ward identities method in the deep IR
Vincent Lahoche, Dine Ousmane Samary
This paper, as a continuation of our previous investigation [arXiv:2403.07577] aims to study the glassy random matrices with quenched Wigner disorder. In this previous work, we hav…
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…
Noether's currents for conformable fractional scalar field theories
Jean-Paul Anagonou, Vincent Lahoche, Dine Ousmane Samary
The construction of fractional derivatives with the right properties for use in field theory is reputed to be a difficult task, essentially because of the absence of a unique defin…
