Probing Neutron Star Crusts with Artificial Neural Networks

Department of Energy, Office of Science — Fri, 08 Nov 2024 16:05:36 EST

The inner crust of a neutron star is characterized by the presence of a neutron superfluid. To accurately predict the properties of neutron matter in this state, researchers make theoretical calculations that typically assume that neutrons form "Cooper pairs." This study used artificial neural networks to make accurate predictions without relying on this assumption.
