  1. 1. Majorana bound states in chains of interacting quantum dots

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Författare :William Samuelson; [2023]
    Nyckelord :quantum dots; superconducting proximity effect; Majorana bound states; Physics and Astronomy;

    Sammanfattning : This thesis concerns the creation of Majorana bound states (MBSs) -- a type of condensed matter excitations theorized to have exotic and technologically valuable properties. In particular, they could be used to store and manipulate quantum information in a protected way, forming the building blocks of a topological quantum computer. LÄS MER

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

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Markus Aspegren; [2020]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Majorana bound states in Rashba nanowire junctions

    L3-uppsats, Uppsala universitet/Materialteori

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

    Sammanfattning : 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. LÄS MER

  5. 4. Simulation of Majorana Bound States in Multi-Band Josephson Junction Nanowires

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Georg Wolgast; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Majorana bound states can be created at the ends of semiconducting nanowires using a combination of proximity-induced superconductivity, spin-orbit coupling and a magnetic eld. By adding a Josephson junction to this nanowire, four Majorana bound states can exist at the same time in the system. LÄS MER

  7. 5. Majorana bound states in inhomogeneous nanowires

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Johan Ekström; [2017]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Majorana bound states are in condensed matter physics quasiparticle excitations which can be found in so-called topological superconductors. They have lately received much attention since they have been predicted to be partly immune to decoherence and therefore suitable for quantum computation. LÄS MER
