Absence of a shell closure in Sn
Francesca Bonaiti, Bingcheng He, Gaute Hagen +1
There are conflicting theoretical results about the presence of a shell closure in the neutron-rich nucleus Sn. We address this controversy by performing ab initio computat…
Saturation of Nuclear Binding from Lattice Hamiltonians
Maxwell Rothman, Gaute Hagen, Matthias Heinz +1
There is a conundrum regarding the binding of particles in nuclei. On one hand, auxiliary-field Monte Carlo simulations of Hamiltonians on discrete spatial lattices proposed t…
Linking Electromagnetic Moments to Nuclear Interactions with a Global Physics-Driven Machine-Learning Emulator
Jose M. Munoz, Antoine Belley, Andreas Ekström +3
Understanding how specific components of the nuclear interaction shape observable properties of atomic nuclei remains a central challenge in nuclear structure research. While previ…
Chiral interactions and superfluidity in the calcium isotopic chain
A. Scalesi, A. Ekström, C. Forssén +1
We perform ab initio calculations of three-point mass differences in the odd- and even-mass Ca isotopes to probe nuclear superfluidity via empirical neutron pairing gaps.…
Dynamics of density fluctuations in atomic nuclei
Francesca Bonaiti, Gaute Hagen, Thomas Papenbrock
We study the spatiotemporal patterns of density fluctuations in O and Ca using nuclear interactions from chiral effective field theory and the time-dependent coupl…
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…
