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

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

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

    Abstract : 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. READ MORE

  3. 2. 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

  4. 3. 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.

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

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

    Author : Georg Wolgast; [2017]
    Keywords : Physics and Astronomy;

    Abstract : 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. READ MORE

  6. 5. Majorana bound states in inhomogeneous nanowires

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

    Author : Johan Ekström; [2017]
    Keywords : Physics and Astronomy;

    Abstract : 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. READ MORE
