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…
Open string stub as an auxiliary string field
Harold Erbin, Atakan Hilmi Fırat
Witten's open string field theory with a generalized version of stubs is reformulated as a cubic string field theory using an auxiliary string field. The gauge symmetries and equat…
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…
Renormalization in the neural network-quantum field theory correspondence
Harold Erbin, Vincent Lahoche, Dine Ousmane Samary
A statistical ensemble of neural networks can be described in terms of a quantum field theory (NN-QFT correspondence). The infinite-width limit is mapped to a free field theory, wh…
Characterizing 4-string contact interaction using machine learning
Harold Erbin, Atakan Hilmi Fırat
The geometry of 4-string contact interaction of closed string field theory is characterized using machine learning. We obtain Strebel quadratic differentials on 4-punctured spheres…
Closed string theory without level-matching at the free level
Harold Erbin, Maxime Médevielle
In its traditional form, the string field in closed string field theory is constrained by the level-matching condition, which is imposed beside the action. By analogy with the simi…
