Symmetry-projected Hartree-Fock-Bogoliubov Equations
Symmetry-projected Hartree-Fock-Bogoliubov (HFB) equations are derived using the variational ansatz for the generalized one-body density-matrix in the Valatin form. It is shown that the projected-energy functional can be completely expressed in terms of the HFB density-matrix and the pairing-tensor. The variation of this projected-energy is shown to result in HFB equations with modified express...
متن کاملContact Pairing Interaction for the Hartree- Fock-bogoliubov Calculations
Properties of density-dependent contact pairing interactions in nuclei are discussed. It is shown that the pairing interaction that is intermediate between surface and volume pairing forces gives the pairing gaps that are compatible with the experimental odd-even mass staggering. Results of the deformed Hartree-Fock-Bogoliubov calculations for this \mixed" pairing interaction, and using the tra...
متن کاملHartree-Fock ground state of the three-dimensional electron gas.
In 1962, Overhauser showed that within Hartree-Fock (HF) the electron gas is unstable to a spin-density wave state. Determining the true HF ground state has remained a challenge. Using numerical calculations for finite systems and analytic techniques, we study the unrestricted HF ground state of the three-dimensional electron gas. At high density, we find broken spin symmetry states with a near...
متن کاملCranked Hartree - Fock - Bogoliubov Calculation for Rotating Bose - Einstein Condensates
Naoki Onishi Department of Information System, Tokyo International University 1-13-1 Matoba-kita, Kawagoe, Saitama, 350-1197, Japan (Dated: February 1, 2008) Abstract A rotating bosonic many-body system in a harmonic trap is studied with the 3D-Cranked Hartree-Fock-Bogoliubov method at zero temperature, which has been applied to nuclear manybody systems at high spin. This method is a variationa...
متن کاملGapless Hartree-Fock-Bogoliubov Approximation for Bose Gases
A dilute Bose system with Bose-Einstein condensate is considered. It is shown that the Hartree-Fock-Bogolubov approximation can be made both conserving as well as gapless. This is achieved by taking into account all physical normalization conditions, that is, the normalization condition for the condensed particles and that for the total number of particles. Two Lagrange multipliers, introduced ...
