  1. 1. Charge Transport in Semiconductor Nanowire Quantum Devices: From Single Quantum Dots to Topological Superconductors

    Author : Mingtang Deng; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multiple Andreev reflection; SQUID; Proximity effect; the Josephson effect; Cooper pair; the Kondo effect; the Zeeman effect; Quantum dot; InSb; Nanowires; Transport; Fysicumarkivet A:2013:Deng; Majorana bound state; Yu-Shiba-Rusinov state; Andreev bound state;

    Abstract : This thesis focuses on charge transport in semiconductor InSb nanowire quantum devices, including the electron transport, the hole transport, and the Cooper pair transport. Devices in which InSb semiconductor nanowire quantum dots are coupled with normal metals, superconductors or the proximity effect induced topological superconductors are fabricated and measured.

  2. 2. Quantum Transport in Superconductor-Semiconductor Nanowire Hybrid Devices

    University dissertation from Solid State Physics, Lund University

    Author : Chunlin Yu; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2018-09-06]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Nanowire; InSb; Transport; Quantum dot; Majorana bound states; Andreev bound states; the Kondo effect; Superconductivity; Fysicumarkivet A:2018:Yu;

    Abstract : In this thesis, we study quantum transport properties of superconductor-semiconductor nanowire hybrid devices. We mainly focus on the quantum transport in InSb nanowire Josephson quantum dot devices, i.e. quantum dots coupled to two pieces of superconductors. READ MORE

  3. 3. The one-dimensional Kondo Lattice in the Majorana Fermion representation

    University dissertation from Göteborg : University of Gothenburg

    Author : Matteo Bazzanella; Göteborgs universitet.; Gothenburg University.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Majorana fermions; kondo lattice; path integral; spin-selective kondo insulator;

    Abstract : This thesis analyses the possibilities offered by the representation of quantum mechanical operators in terms of Majorana fermions. These objects can be imagined as algebraic constituents of the fermionic degrees of freedom, allowing for a different representation of many Hamiltonians. READ MORE
