Low - Momentum Nucleon - Nucleon Potential and Hartree - Fock Calculations
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...
متن کاملParallel scalability of Hartree-Fock calculations.
Quantum chemistry is increasingly performed using large cluster computers consisting of multiple interconnected nodes. For a fixed molecular problem, the efficiency of a calculation usually decreases as more nodes are used, due to the cost of communication between the nodes. This paper empirically investigates the parallel scalability of Hartree-Fock calculations. The construction of the Fock m...
متن کاملMomentum distribution of relativistic nuclei with Hartree-Fock mesonic correlations
The impact of Hartree-Fock correlations on the nuclear momentum distribution is studied in a fully relativistic one boson exchange model. Hartree-Fock equations are exactly solved to first order in the coupling constants. The renormalization of the Dirac spinors in the medium is shown to affect the momentum distribution, as opposed to what happens in the non-relativistic case. The unitarity of ...
متن کاملSkyrme-force time-dependent Hartree-Fock calculations with axial symmetry
We discuss axially symmetric time-dependent Hartree-Fock calculations using a finite-range modification of the Skyrme energy functional. The finite-difference forms of the coordinate-space time-dependent Hartree-Fock equations, the method of time evolution, and other numerical aspects are presented. Detailed results for 84Krinduced deep-inelastic collisions with 208Pb at E 1,b = 494 MeV and wit...
متن کاملHartree-Fock-Bogolyubov calculations with Gaussian expansion method
We extensively develop an algorithm of implementing the Hartree-Fock-Bogolyubov calculations, in which the Gaussian expansion method is employed. This algorithm is advantageous in describing the energy-dependent exponential and oscillatory asymptotics of the quasiparticle wave functions at large r, and in handling various effective interactions including those with finite ranges. We apply the p...
