1. A mean-field approach to attractive few-body Fermi gas
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysikSammanfattning : 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.
