We define the new description of the electromagnetic current to hold the current conservation in the momentum-dependent Dirac fields from the Ward Takahashi identity. To describe the momentum-dependence we solve the relativistic Hartree-Fock approximation by using the one-pion exchange. In addition we discuss on contribution from the one-pion exchange current and the core polarization. It is sh...

Following the experimental discovery of the superdeformed(SD) band in Zn, we calculate several low-lying SD bands in neutron-deficient 30Zn isotopes using Relativistic Mean Field model. For comparison, we also perform nonrelativistic Skyrme-Hartree-Fock calculation of the SD bands in Zn. Both models give somewhat smaller moments of inertia than the observed ones, but we can see some qualitative...

Quasielastic electromagnetic and parity-violating electron scattering response functions of relativistic nuclear matter are reviewed. The roles played by the Hartree-Fock field and by nuclear correlations in the Random Phase Approximation (treated within the continued fraction scheme) are illustrated. The parity-violating responses of nuclei to polarized electrons are also revisited, stressing ...

Recently, an O(3) type of effective action was presented for the quantum Hall ferromagnet, which accounts for bag formation observed in microscopic Hartree-Fock calculations. We apply this action in the soliton sector and compare with Hartree-Fock results. We find good agreement over the whole parameter range where skyrmions exist. The standard minimal O(3) model cannot explain the bag and has ...

We present solutions of the coupled, non-relativistic S1D1 gap equations for neutron-proton pairing in symmetric nuclear matter, and estimate relativistic effects by solving the same gap equations modified according to minimal relativity and using single-particle energies from a DiracBrueckner-Hartree-Fock calculation. As a main result we find that relativistic effects decrease the value of the...

We formulate charge transfer model for a single doped spin ladder, relevant for the intrinsically doped plane of coupled spin ladders in Sr3Ca11Cu24O41. Assuming the presence of the experimentally observed charge order in the system we solve the model using Hartree-Fock approximation. Our results show the profound stability of the Zhang-Rice singlets with respect to other configurations of dope...

A low-momentum nucleon-nucleon (N N) potential V low−k is derived from modern realistic N N potentials by integrating out the high-momentum modes. The smooth V low−k may be used as input for nuclear structure calculations instead of the usual Brueckner G matrix. Such an approach eliminates the energy dependence one finds in the G-matrix approach, allowing this interaction to be used directly in...

Using Thomas-Fermi-Dirac equation within the exchange-correlation scheme and a Z-dependent trial solution, the ground state binding energy for neutral, positively, and negatively charged atoms are calculated. Comparing to the results obtained in earlier works, the values of the binding energy estimated here for both light and heavy atoms agree nicely with the Hartree-Fock values. We have also c...

This report concerns the energy of neutron-matter for densities below 0.15fm and temperatures at and below 10MeV . Separable NN-interactions are obtained by inverse scattering from the experimental phase-shifts with specified momentum cut-offs Λ. Results of Brueckner-Bloch-DeDomicis as well as finite temperature Green’s function calculations show independence of cut-off for Λ ≥ 3. Agreement wit...
