The dipole strength distribution of He and decay characteristics
C. Lehr, T. Aumann, M. Duer +91
The weak binding and spatially extended neutron densities characteristic of drip-line nuclei give rise to a distinctive low-energy dipole response. The drip-line nucleus He is…
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…
Computing nuclear response functions with time-dependent coupled-cluster theory
Francesca Bonaiti, Cody Balos, Kyle Godbey +3
We compute nuclear response functions by solving the time-dependent A-body Schrödinger equation, recording the time-dependent transition moment and extracting spectral information…
Structure of the doubly magic nuclei Pb and Pb from ab initio computations
Francesca Bonaiti, Gaute Hagen, Thomas Papenbrock
Theoretical studies indicate that the superheavy neutron-rich nucleus Pb is doubly magic and at the neutron drip line. While its density distributions and si…
Exactness of the normal-ordered two-body truncation of three-nucleon forces
Maxwell Rothman, Ben Johnson-Toth, Francesca Bonaiti +3
Reference-state-based many-body methods start from Hamiltonians that are normal ordered with respect to the reference state. In low-energy nuclear physics applications normal-order…
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…
Data-driven analysis of dipole strength functions using artificial neural networks
Weiguang Jiang, Tim Egert, Sonia Bacca +2
We present a data-driven analysis of dipole strength functions across the nuclear chart, employing an artificial neural network to model and predict nuclear dipole responses. We tr…
Recent advances in coupled cluster computations of open-shell atomic nuclei
Francesco Marino, Francesca Bonaiti, Sonia Bacca +5
In this contribution, we report on recent progress in coupled-cluster simulations of open-shell atomic nuclei using interactions consistently derived from chiral effective field th…
Electric dipole polarizability of Ni
I. Brandherm, F. Bonaiti, P. von Neumann-Cosel +10
The electric dipole strength distribution in Ni between 6 and 20 MeV has been determined from proton inelastic scattering experiments at very forward angles at RCNP, Osaka.…
Electromagnetic observables of open-shell nuclei from coupled-cluster theory
Francesca Bonaiti, Sonia Bacca, Gaute Hagen +1
We develop a new method to describe electromagnetic observables of open-shell nuclei with two nucleons outside a closed shell. This approach combines the equation-of-motion coupled…
Low-energy dipole strength in 8He
Francesca Bonaiti, Sonia Bacca
In this work, we present new ab initio coupled-cluster calculations of dipole-excited state properties of 8He based on the chiral effective field theory interaction 1.8/2.0 (EM). W…

R. W. Fearick, P. von Neumann-Cosel, S. Bacca +14
The electric dipole strength distribution in Ca between 5 and 25 MeV has been determined at RCNP, Osaka, from proton inelastic scattering experiments at very forward angles.…
Effective field theory analysis of the Coulomb breakup of the one-neutron halo nucleus 19C
Pierre Capel, Daniel R. Phillips, Andrew Andis +29
We analyse the Coulomb breakup of 19C measured at 67A MeV at RIKEN. We use the Coulomb-Corrected Eikonal (CCE) approximation to model the reaction and describe the one-neutron halo…
Uncertainty quantification in electromagnetic observables of nuclei
Bijaya Acharya, Sonia Bacca, Francesca Bonaiti +2
We present strategies to quantify theoretical uncertainties in modern ab-initio calculations of electromagnetic observables in light and medium-mass nuclei. We discuss how uncertai…
