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 co…
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…
NuLattice: Ab initio computations of atomic nuclei on lattices
M. Rothman, B. Johnson-Toth, G. Hagen +2
We introduce NuLattice, a Python software package for ab initio computations of atomic nuclei on lattices. The computational tools consist of Hartree Fock, the coupled cluster meth…
The neutron dripline in calcium isotopes from a chiral interaction
B. S. Hu, A. Ekström, C. Forssén +4
Interactions derived from effective field theories of quantum chromodynamics have thus far failed to bind calcium nuclei beyond neutron number , while nuclear density functio…
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…
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…
