  1. 11. First Principle Calculations & Inelastic Neutron Scattering on the Single-Crystalline Superconductor LaPt2Si2

    University essay from KTH/Materialvetenskap

    Author : Mazza Federico; [2020]
    Keywords : Superconductivity; LaPt2Si2; Inelastic Neutron Scattering; Charge Density Wave; Band Structure Calculations; DFT; SNIC; J-PARC; Supraledning; LaPt2Si2; neutronspridning; neutronspektroskopi; Bandberäkningar; DFT; J-PARC;

    Abstract : This work presents a comprehensive study on single crystalline LaPt2Si2, in which superconductivity and a charge density wave (CDW) coexist. The usage of density functional theory (DFT) modeling and Inelastic Neutron Scattering has been the primary form of investigation, in order to determine all the characteristic features of the sample taken under consideration.

  2. 12. Characterization of InAs-Al semiconductor-superconductor hybrid devices

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Markus Aspegren; [2020]
    Keywords : quantum dot; superconductivity; quantum transport; josephson junction; spectroscopy; yu-shiba-rusinov; hybrid devices; sub-gap states; quantum computer; majorana bound state; bogoliubov quasiparticle; Physics and Astronomy;

    Abstract : 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

  3. 13. Majorana bound states in Rashba nanowire junctions

    University essay from Uppsala universitet/Materialteori

    Author : Lucas Baldo Mesa Casa; [2020]
    Keywords : Topological superconductivity; Rashba nanowires; Majorana Bound States;

    Abstract : Nanowires with Rashba spin-orbit coupling represent a promising platform for the realization of one-dimensional topological superconductivity and Majorana bound states. In this work we investigate Majorana bound states in hybrid normal-superconductor and short superconductor-normal-superconductor junctions based on nanowires with Rashba spin-orbit coupling.

  4. 14. Combining the GW Approximation with the Hubbard I Approximation for strongly correlated materials

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

    Author : Torsten Strunck; [2019]
    Keywords : GWA; GW Approximation; HIA; Hubbard I Approximation; Hubbard-I Approximation; Hubbard model; DMFT; Dynamical Mean Field Theory; strongly correlated materials; electron correlations; solid state physics; Physics and Astronomy;

    Abstract : In this thesis, the GW approximation (GWA, Green's function G times screened interaction W) and the Hubbard I approximation (HIA) are combined in a non-self-consistent one-shot calculation to determine the electronic structure of a one-dimensional strongly-correlated model. The scheme was chosen to incorporate both screening effects through the GWA and strong on-site correlations through the atomic HIA. READ MORE
