Multi-Body Entanglement and Information Rearrangement in Nuclear Many-Body Systems
S. Momme Hengstenberg, Caroline E. P. Robin, Martin J. Savage
We examine how effective-model-space (EMS) calculations of nuclear many-body systems rearrange and converge multi-particle entanglement. The generalized Lipkin-Meshkov-Glick (LMG)…
Nuclear Forces for Precision Nuclear Physics -- a collection of perspectives
Ingo Tews, Zohreh Davoudi, Andreas Ekström +42
This is a collection of perspective pieces contributed by the participants of the Institute of Nuclear Theory's Program on Nuclear Physics for Precision Nuclear Physics which was h…
Beyond-mean-field calculations of allowed and first-forbidden decays of -process waiting-point nuclei
Caroline Robin, Elena Litvinova, Gabriel Martínez-Pinedo
-decay rates of neutron-rich nuclei, in particular those located at neutron shell closures, play a central role in simulations of the heavy-element nucleosynthesis and resulting…
Impact of complex many-body correlations on electron capture in thermally excited nuclei around Ni
Elena Litvinova, Caroline Robin
We link complex many-body correlations, which play a decisive role in the structural properties of atomic nuclei, to the electron capture occurring during star evolution. The recen…
Entanglement Rearrangement in Self-Consistent Nuclear Structure Calculations
Caroline Robin, Martin J. Savage, Nathalie Pillet
Entanglement properties of He and He are investigated using nuclear many-body calculations, specifically the single-nucleon entanglement entropy, and the two-nucleon mutual…
