Ab initio Bogoliubov coupled cluster theory for open-shell nuclei
Angelo Signoracci, Thomas Duguet, Gaute Hagen +1
Ab initio many-body methods address closed-shell nuclei up to mass A ~ 130 on the basis of realistic two- and three-nucleon interactions. Several routes to address open-shell nucle…
Effects of three-nucleon forces and two-body currents on Gamow-Teller strengths
A. Ekström, G. R. Jansen, K. A. Wendt +5
We optimize chiral interactions at next-to-next-to leading order to observables in two- and three-nucleon systems, and compute Gamow-Teller transitions in carbon-14, oxygen-22 and…
Ab-initio coupled-cluster effective interactions for the shell model: Application to neutron-rich oxygen and carbon isotopes
G. R. Jansen, J. Engel, G. Hagen +2
We derive and compute effective valence-space shell-model interactions from ab-initio coupled-cluster theory and apply them to open-shell and neutron-rich oxygen and carbon isotope…
