Calculations for nuclear matter and finite nuclei within and beyond energy-density-functional theories through interactions guided by effective field theory

We propose a novel idea to construct an effective interaction under energy-density-functional (EDF) theories which is adaptive the enlargement of model space. Guided by field theory principles, iterations interactions as well enlargements space through particle-hole excitations are carried out for infinite nuclear matter and selected closed-shell nuclei ($^{4}\mathrm{He}, ^{16}\mathrm{O}, ^{40}\mathrm{Ca}, ^{56}\mathrm{Ni}$, $^{100}\mathrm{Sn}$) up next-to-leading order. Our approach provides new way handling finite within same scheme, with advantages from both EDF ab initio approaches.
