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 NanoscienceSammanfattning : 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
2. Fabrication Development of InAs-Pb Nanodevices
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Research groups around the world are looking to develop a qubit protected from decoherence for achieving quantum advantage in computations. This would have huge impact on the modern world. The applications are many from drug development to cryptography and many more elds. LÄS MER
3. Characterization of InAs-Al semiconductor-superconductor hybrid devices
Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenSammanfattning : 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. Majorana bound states in Rashba nanowire junctions
L3-uppsats, Uppsala universitet/MaterialteoriSammanfattning : 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. Discussions on Dai-Freed Anomalies
Master-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : In both field theories of high energy physics and field theories of condensed matter theories anomalies have been imposing constraints and bringing up new theories. While the perturbational and local anomalies from triangle diagrams are well-developed, we follow and review two works leading to non-perturbational global anomalies both related with Atiyah-Patogi-Sieger (APS) index theorem.
