1. 1. Symmetry restoration of HFB states using projection

   University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Author : Carl Frostenson; [2019]
   Keywords : Symmetry restoration; Projection; HFB; nuclear physics; nuclear; Physics and Astronomy;

   Abstract : The restoration of particle number and angular momentum symmetry using projection operators has been theoretically investigated for mean-field Hartree-Fock-Bogoliubov (HFB) states. A computer code for the projection of particle number was then implemented. READ MORE

3. 2. A mean-field approach to attractive few-body Fermi gas

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

   Author : Morten Piibeleht; [2016]
   Keywords : HFB; hartree-fock-bogoliubov; fermi gas; higgs mode; QRPA; quasiparticles; random phase approximation; Physics and Astronomy;

   Abstract : Quantum many-body systems can be studied theoretically from first principles using microscopic models, but the computational cost of numerically exact calculations increases exponentially with the number of particles and the complexity of the interaction, limiting the systems that can be analysed. The Hartree-Fock-Bogoliubov (HFB) and quasiparticle random phase approximation (QRPA) methods, heavily used in nuclear physics, rely on mean-field approximations but scale more favourably with increasing system size and complexity.
