Abstract: The ground-state energies and radii for $^{4}$He, $^{16}$O, and $^{40}$Ca are calculated with the unitary-model-operator approach (UMOA). In the present study, we employ the similarity renormalization group (SRG) evolved nucleon-nucleon ($NN$) and three-nucleon ($3N$) interactions… read more here.

Abstract: In the earlier unitary-model-operator approach (UMOA), one-body correlations have been taken into account approximately by the diagonalization of unitary-transformed Hamiltonians in the $0\text{p}0\text{h}$ and $1\text{p}1\text{h}$ space. With this prescription, the dependence of the harmonic-oscillator energy… read more here.
