S ep 1 99 7 Relativistic Brueckner - Hartree - Fock calculations with explicit intermediate negative energy states
In a relativistic Brueckner-Hartree-Fock calculation we include explicit negative-energy states in the two-body propagator. This is achieved by using the Gross spectator-equation, modified by medium effects. Qualitatively our results compare well with other RBHF calculations. In some details significant differences occur, e.g, our equation of state is stiffer and the momentum dependence of the ...
متن کاملAsymmetric Nuclear Matter from Extended Brueckner-Hartree-Fock Approach
The properties of isospin-asymmetric nuclear matter have been investigated in the framework of the extended Brueckner-Hartree-Fock approximation at zero temperature. Selfconsistent calculations using the Argonne V14 interaction are reported for several asymmetry parameters β = N−Z A ranging from symmetric nuclear matter to pure neutron matter. The binding energy per nucleon fulfills the β law i...
متن کاملBrueckner-Hartree-Fock study of circular quantum dots
We calculate ground state energies in the Brueckner-Hartree-Fock theory for N electrons with N 20 confined to a circular quantum dot and in presence of a static magnetic field. Comparison with the predictions of Hartree-Fock, local-spin-density and exact configuration-interaction theories is made. We find that the correlations taken into account in Brueckner-Hartree-Fock calculations give an im...
متن کاملHartree Fock Calculations in the Density Matrix Expansion Approach
The density matrix expansion is used to derive a local energy density functional for finite range interactions with a realistic meson exchange structure. Exchange contributions are treated in a local momentum approximation. A generalized Slater approximation is used for the density matrix where an effective local Fermi momentum is chosen such that the next to leading order off-diagonal term is ...
متن کاملStrange nuclear matter within Brueckner-Hartree-Fock theory
We have developed a formalism for microscopic Brueckner-type calculations of dense nuclear matter that includes all types of baryon–baryon interactions and allows to treat any asymmetry on the fractions of the different species (n, p,Λ,Σ−,Σ0,Σ+,Ξ− and Ξ0). We present results for the different single–particle potentials focussing on situations that can be relevant in future microscopic studies o...
