Nuclear energy-density functional (EDF) approach for calculating the response functions based on Skyrme-Kohn-Sham-Bogoliubov method and the like-particle quasiparticle-random-phase approximation (QRPA) and the proton-neutron QRPA.

Ab initio studies of the double-Gamow-Teller transition and its correlation with neutrinoless double-β decay

Ab initio many body methods by importance-truncated no-core shell model (IT-NCSM) with GXPF1A interaction, valence-space in-medium similarity renormalization group method (VSIMSRG) with EM1.8/2.0 interaction, and in-medium generator coordinate method (IM-GCM). ⁶He, ¹⁰Be, ¹⁴C, ¹⁸O, ²²Ne, ²⁶Mg, ³⁰Si, ³⁴S, ³⁸Ar, ^42,44Ca, ⁴⁶Ti, ⁵⁰Cr; 2β^- decay mode forbidden for these nuclei due to negative Q values, however, on query, authors mentioned that these nuclei were included for NMEs for 0νββ decays as these involved the same decay operators that determine the allowed decay rates, thus helpful to benchmark many-body approaches for the nuclear matrix elements of neutrinoless double beta decay.
