Functional renormalization group for signal detection and stochastic ergodicity breaking
Harold Erbin, Riccardo Finotello, Bio Wahabou Kpera +2
Signal detection is one of the main challenges of data science. As it often happens in data analysis, the signal in the data may be corrupted by noise. There is a wide range of tec…
Gravitational action for a massive Majorana fermion in 2d quantum gravity
Corinne de Lacroix, Harold Erbin, Vincent Lahoche
We compute the gravitational action of a free massive Majorana fermion coupled to two-dimensional gravity on compact Riemann surfaces of arbitrary genus. The structure is similar t…
Anomalous higher order Ward identities in tensorial group field theories without closure constraint
Bio Wahabou Kpera, Vincent Lahoche, Dine Ousmane Samary +1
The Ward-Takahashi identities are considered as the generalization of the Noether currents available to quantum field theory and include quantum fluctuation effects. Usually, they…
Stochastic melonic kinetics with random initial conditions
Bio Wahabou Kpera, Vincent Lahoche, Dine Ousmane Samary
The probability laws associated with random tensors or tensor field theories are traditionally equilibrium distributions. In this paper, we consider a stochastic point of view, and…
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…
