Ab initio calculations of two-neutrino and neutrinoless double- decay of Ca and related Gamow-Teller strength distributions
Zhen Li, Lotta Jokiniemi, Achim Schwenk
The paper uses ab initio VS‑IMSRG calculations with chiral EFT interactions to predict two‑neutrino and neutrinoless double‑beta decay rates of ⁴⁸Ca, showing that an enlarged d₃/₂…

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 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 -process nucleosynthesis. We present first ab initio ca…
