| Non-empirical pairing energy functional in nuclear matter and finite nuclei |
| K. Hebeler, T. Duguet, T. Lesinski, A. Schwenk |
| We study $^{1}$S$_{0}$ pairing gaps in neutron and nuclear matter as well as in finite nuclei on the basis of microscopic two-nucleon interactions. Special attention is paid to the consistency of the pairing interaction and normal self-energy contributions. We find that pairing gaps obtained from low-momentum interactions depend only weakly on approximation schemes for the normal self-energy, required in present energy-density functional calculations, while pairing gaps from hard potentials are very sensitive to the effective-mass approximation scheme. |
