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 …

Is the number of trainable parameters all that actually matters?
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
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-…
