Theory Framework for Medium-Mass Muonic Atoms
S. Rathi, I. A. Valuev, Z. Sun +4
We present a state-of-the-art theoretical approach for computing bound-state energies in muonic atoms, incorporating improved quantum electrodynamics effects and nuclear polarizati…
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…
Coupled-cluster theory for strong entanglement in nuclei
Z. H. Sun, G. Hagen, T. Papenbrock
Atomic nuclei can exhibit shape coexistence and multi-reference physics that enters in their ground states, and to accurately capture the ensuing correlations and entanglement is c…
How chiral forces shape neutron-rich Ne and Mg nuclei
Andreas Ekström, Christian Forssén, G. Hagen +3
We compute the structure of the exotic even nuclei Ne and Mg using interactions from chiral effective field theory (EFT). Our results for the ground-state rotat…
Shell-model coupled-cluster method for open-shell nuclei
Z. H. Sun, T. D. Morris, G. Hagen +2
We present an approach to derive effective shell-model interactions from microscopic nuclear forces. The similarity-transformed coupled-cluster Hamiltonian decouples the single-ref…
