#### Consistency between SU(3) and SU(2) covariant baryon chiral perturbation theory for the nucleon mass

(Elsevier, 2017)

Treating the strange quark mass as a heavy scale compared to the light quark mass, we perform a matching of the nucleon mass in the SU(3) sector to the two-flavor case in covariant baryon chiral perturbation theory. The ...

#### Fully self-consistent relativistic Brueckner-Hartree-Fock theory for finite nuclei

(American Physical Society, 2017)

Starting from the relativistic form of the Bonn potential as a bare nucleon-nucleon interaction, the full relativistic Brueckner-Hartree-Fock (RBHF) equations are solved for finite nuclei in a fully self-consistent basis. ...

#### Influence of pairing correlations on the radius of neutron-rich nuclei

(American Physical Society, 2017)

The influence of pairing correlations on the neutron root mean square (rms) radius of nuclei is investigated in the framework of self-consistent Skyrme Hartree-Fock-Bogoliubov calculations. The continuum is treated ...

#### Relativistic Brueckner-Hartree-Fock theory in nuclear matter without the average momentum approximation

(American Physical Society, 2018)

Brueckner-Hartree-Fock theory allows one to derive the G matrix as an effective interaction between nucleons in the nuclear medium. It depends on the center-of-mass momentum P of the two particles and on the two relative ...

#### Relativistic Brueckner-Hartree-Fock theory for neutron drops

(American Physical Society, 2018)

Neutron drops confined in an external field are studied in the framework of relativistic Brueckner-Hartree-Fock theory using the bare nucleon-nucleon interaction. The ground-state energies and radii of neutron drops with ...

#### Spectroscopic study of the possibly triaxial transitional nucleus 75Ge

(American Physical Society, 2018)

The collective structures of 75Ge have been studied for the first time via the 74Ge(α,2p1n) 75Ge fusionevaporation
reaction. Two negative-parity bands and one tentative positive-parity band built on the νp1/2, νf5/2,
and ...

#### Solving Dirac equations on a 3D lattice with inverse Hamiltonian and spectral methods

(American Physical Society, 2017)

A new method to solve the Dirac equation on a 3D lattice is proposed, in which the variational collapse problem is avoided by the inverse Hamiltonian method and the fermion doubling problem is avoided by performing spatial ...

#### Towards the improvement of spin-isospin properties in nuclear energy density functionals

(IOP Publishing, 2016)

We address the problem of improving existing nuclear Energy Density Functionals (EDFs) in the spin-isospin channel. For that, we propose two different ways. The first one is to carefully take into account in the fitting ...

#### Understanding the chiral geometry with K-Plot and Azimuthal-Plot

(Jagellonian University, 2018)

The chiral geometry of the angular momentum in the intrinsic frame is extracted from angular momentum projected wave functions in the laboratory frame by the K-Plot and Azimuthal-Plot. The method is demonstrated by an ...

#### Self-consistent relativistic quasiparticle random-phase approximation and its applications to charge-exchange excitations

(American Physical Society, 2017)

The self-consistent quasiparticle random-phase approximation (QRPA) approach is formulated in the canonical single-nucleon basis of the relativistic Hatree–Fock–Bogoliubov (RHFB) theory. This approach is applied to study ...
