Neutron drip line 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…
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…
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…
A nuclear mass model rooted in chiral effective field theory
C. Mishra, A. Ekström, G. Hagen +3
We develop a nuclear mass model that is based on chiral effective field theory at next-to-next-to leading order. Nuclear binding energies are computed via the Hartree-Fock method u…
Structure of odd-mass Ne, Na, and Mg nuclei
Z. H. Sun, T. R. Djärv, G. Hagen +2
The island of inversion is a region of neutron-rich nuclei that are deformed in their ground states. In this region, less is known about the energy levels of odd-mass nuclei, how t…
Ab initio computations from Ni towards Ca along neutron number
B. S. Hu, Z. H. Sun, G. Hagen +2
We present coupled-cluster computations of nuclei with neutron number "south" of Ni using nucleon-nucleon and three-nucleon forces from chiral effective field theory.…
Ab initio computations of strongly deformed nuclei around Zr
B. S. Hu, Z. H. Sun, G. Hagen +1
Nuclei around are strongly deformed and exhibit coexistence of shapes. These phenomena have challenged nuclear models. Here we perform ab initio coupled-clus…
Multiscale physics of atomic nuclei from first principles
Z. H. Sun, A. Ekström, C. Forssén +3
Atomic nuclei exhibit multiple energy scales ranging from hundreds of MeV in binding energies to fractions of an MeV for low-lying collective excitations. As the limits of nuclear…
Magnetic dipole transition in Ca
B. Acharya, B. S. Hu, S. Bacca +3
The magnetic dipole transition strength of Ca is dominated by a single resonant state at an excitation energy of 10.23 MeV. Experiments disagree about and th…
Coupled-cluster calculations of neutrinoless double-beta decay in Ca
S. J. Novario, P. Gysbers, J. Engel +6
We use coupled-cluster theory and nuclear interactions from chiral effective field theory to compute the nuclear matrix element for the neutrinoless double-beta decay of Ca.…
Cloud Quantum Computing of an Atomic Nucleus
E. F. Dumitrescu, A. J. McCaskey, G. Hagen +6
We report a quantum simulation of the deuteron binding energy on quantum processors accessed via cloud servers. We use a Hamiltonian from pionless effective field theory at leading…
Evolution of shell structure in neutron-rich calcium isotopes
G. Hagen, M. Hjorth-Jensen, G. R. Jansen +2
We employ interactions from chiral effective field theory and compute the binding energies and low-lying excitations of calcium isotopes with the coupled-cluster method. Effects of…
