1. Characterization of InAs-Al semiconductor-superconductor hybrid devices
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : In this thesis we study charge and spin transport through InAs-Al nanowire superconductor-semiconductor hybrid devices. We focus on assessing the quality of the InAs-Al contact interface when using a weak HCl acid to wet-etch the nanowire surface prior to metal evaporation. READ MORE

2. A mean-field approach to attractive few-body Fermi gas
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysikAbstract : 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.

3. Numerical Studies of Vortex Core States in Type II Superconductors
University essay from Institutionen för fysikAbstract : In this thesis, we study an isolated vortex in an s-wave superconductor by solving the Bogoliubov-de Gennes equations self-consistently on a disc. We calculate the order parameter and supercurrent profiles, as well as the distribution of quasiparticle states. READ MORE
