Neutrino decoherence in presence of strong gravitational fields

A Chatelain, MC Volpe - Physics Letters B, 2020 - Elsevier
We explore the impact of strong gravitational fields on neutrino decoherence. To this aim, we
employ the density matrix formalism to describe the propagation of neutrino wave packets …

Helicity coherence in binary neutron star mergers and nonlinear feedback

A Chatelain, C Volpe - Physical Review D, 2017 - APS
Neutrino flavor conversion studies based on astrophysical environments usually implement
neutrino mixings, neutrino interactions with matter, and neutrino self-interactions. In …

Lighton optical processing unit: Scaling-up AI and HPC with a non von neumann co-processor

…, I Carron, C Chaintoutis, A Chatelain… - arXiv preprint arXiv …, 2021 - arxiv.org
We introduce LightOn's Optical Processing Unit (OPU), the first photonic AI accelerator chip
available on the market for at-scale Non von Neumann computations, reaching 1500 …

PAGnol: An extra-large French generative model

…, B Pannier, F Boniface, A Chatelain… - arXiv preprint arXiv …, 2021 - arxiv.org
Access to large pre-trained models of varied architectures, in many different languages, is
central to the democratization of NLP. We introduce PAGnol, a collection of French GPT …

Neutrino propagation in binary neutron star mergers in presence of nonstandard interactions

A Chatelain, MC Volpe - Physical Review D, 2018 - APS
We explore the impact of nonstandard interactions on neutrino propagation in accretion disks
around binary neutron star merger remnants. We show flavor evolution can be significantly …

Is the number of trainable parameters all that actually matters?

A Chatelain, A Djeghri, D Hesslow… - I (Still) Can't Believe …, 2022 - proceedings.mlr.press
Recent work has identified simple empirical scaling laws for language models, linking compute
budget, dataset size, model size, and autoregressive modeling loss. The validity of these …

Online Change Point Detection in Molecular Dynamics With Optical Random Features

A Chatelain, E Tommasone, L Daudet, I Poli - arXiv preprint arXiv …, 2020 - arxiv.org
Proteins are made of atoms constantly fluctuating, but can occasionally undergo large-scale
changes. Such transitions are of biological interest, linking the structure of a protein to its …

Neutrino propagation in dense astrophysical environnements: beyond the standard frameworks

A Chatelain - 2018 - theses.hal.science
Since the discovery of neutrino oscillations in vacuum, it has been shown that the presence
of a matter background can greatly modify the flavor evolution. The inclusion of neutrino self-…

Smarter, Better, Faster, Longer: A Modern Bidirectional Encoder for Fast, Memory Efficient, and Long Context Finetuning and Inference

B Warner, A Chaffin, B Clavié, O Weller… - arXiv preprint arXiv …, 2024 - arxiv.org
Encoder-only transformer models such as BERT offer a great performance-size tradeoff for
retrieval and classification tasks with respect to larger decoder-only models. Despite being …
