Optimizing artificial neural networks for dipole strength predictions in light nuclei
Tim Egert, Weiguang Jiang, Sonia Bacca
We present an optimized artificial neural network approach for predicting electric dipole strength functions in nuclei with . Building upon a previous global study [Phys.Re…
From closed shells to open shells: Coupled-cluster calculations of atomic nuclei
F. Marino, F. Bonaiti, P. Demol +6
Coupled-cluster theory is a powerful tool for first-principles calculations of atomic nuclei, enabling accurate predictions of nuclear observables across the Segrè chart. While cou…
Ab initio calculations of monopole sum rules: From finite nuclei to infinite nuclear matter
Francesca Bonaiti, Andrea Porro, Sonia Bacca +2
We compute moments of the isoscalar monopole response of N = Z closed-shell nuclei based on chiral nucleon-nucleon plus three-nucleon interactions. We employ the random phase appro…
Electromagnetic sum rules for 22O from coupled-cluster theory
Francesco Marino, Miriam El Batchy, Sonia Bacca
In this contribution, we discuss recent results on the determination of the electric dipole polarizability for the neutron-rich isotope O within the ab initio framewor…
Bridging reaction theory and nuclear structure in -Ca scattering
Viacheslav Tsaran, Francesco Marino, Sonia Bacca +2
We extend the pion-nucleus multiple-scattering framework to include detailed second-order rescattering dynamics for nuclei with non-zero isospin. To account for intermediate charge…
Structure and dynamics of open-shell nuclei from spherical coupled-cluster theory
Francesco Marino, Francesca Bonaiti, Sonia Bacca +2
We extend the spherical coupled-cluster ab initio method for open-shell nuclei where two nucleons are removed from a shell subclosure. Following the recent implementation of the tw…
