Ab initio calculations of two-neutrino and neutrinoless double- $β$ decay of $^{48}$ Ca and related Gamow-Teller strength distributions

Zhen Li, Lotta Jokiniemi, Achim Schwenk

We present ab initio calculations of two-neutrino double-beta ( $2 ν β β$ ) decay of $^{48}$ Ca and the related Gamow-Teller (GT) strength functions in $^{48}$ Sc using the valence-space…

High-order perturbative calculations of nuclear ground states: Automated evaluation of many-body diagrams

Zhen Li, Alexander Tichai, Achim Schwenk +1

We advance the many-body perturbation theory (MBPT) calculations of the ground-state energy and radius of closed-shell nuclei beyond third order. Using automated diagram generation…

Ab initio calculations of beta-decay half-lives for $N = 50$ neutron-rich nuclei

Zhen Li, Takayuki Miyagi, Achim Schwenk

Beta-decay rates of extreme neutron-rich nuclei remain largely unknown experimentally, while they are critical inputs for $r$ -process nucleosynthesis. We present first ab initio ca…
