When the density of a nuclear system is decreased, homogeneous states undergo the so-called Mott transition towards clusterised states, e.g. alpha clustering, both in nuclei and in nuclear matter. Here we investigate such a quantum phase transition (

International audience; We demonstrate that a committee of deep neural networks is capable of predicting the ground-state and excited energies of more than 1800 atomic nuclei with an accuracy akin to the one achieved by state-of-the-art nuclear energ

International audience; We present the results of a local Lorentz invariance (LLI) test performed with the Cs-133 cold atom clock FO2, hosted at SYRTE. Such a test, relating the frequency shift between Cs-133 hyperfine Zeeman substates with the Loren

We analyze the localization properties of two-body correlations induced by pairing in the framework of relativistic mean field (RMF) models. The spatial properties of two-body correlations are studied for the pairing tensor in coordinate space and fo
