Field theoretical approach for signal detection in nearly continuous positive spectra II: Tensorial data
Vincent Lahoche, Mohamed Ouerfelli, Dine Ousmane Samary +1
The tensorial principal component analysis is a generalization of ordinary principal component analysis, focusing on data which are suitably described by tensors rather than matric…
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…
