Proton-neutron entanglement entropy is shown to track the formation of the island of inversion in Ne, Mg, and Si isotopes, with mutual information revealing stronger proton-neutron correlations in excited states than in ground states.
An artificial neural network generates a new effective interaction jj44b_nn from jj44b, yielding shell model results for proton-rich Zn isotopes that are comparable to the original and closer to experiment in some cases.
FCIQMC is applied to compute ground-state energies and charge radii of ^4He, ^8Be, ^12C and ^16O at sub-percent many-body uncertainty using chiral EFT interactions.
Reviews development of statistical shell model using q-normal forms generated by embedded random matrix ensembles for nuclear level densities and strengths.
