2. 1. The paramagnetic Meissner effect

   Author : Evie Papadopoulou; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; high-temperature superconductivity; Bi-based compounds; paramagnetic Meissner effect; ageing; disordered magnets; chiral-glass; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Abstract : The low field dynamics of some high temperature superconductors have been studied experimentally, using SQUID magnetometry. The research has been focused on the so called Paramagnetic Meissner Effect (PME), a phenomenon seen in some high temperature superconducting cuprates. READ MORE

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

   Author : Mingtang Deng; Fasta tillståndets fysik; []
   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.

5. 3. The proteasome as a target for cancer therapy

   Author : Peter Larsson; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; Cell viability assay; Chemotherapy; Drug repurposing; Genomic and transcriptomic signatures; Prognostic biomarkers; Proteasome; Proteasome genes; Proteasome inhibitors; Drug sensitivity biomarkers; Synergistic effect; Triple-negative breast cancer;

   Abstract : The main objective of this PhD thesis was to evaluate the significance of proteasome genes as prognostic markers for different cancer types and identify specific cancer forms that respond to proteasome inhibition. The proteasome (PSM) plays an important role in maintaining cellular proteostasis and degrades the majority of proteins that require breakdown in the cell. READ MORE

6. 4. Thermoelectric experiments on nanowire-based quantum dots

   Author : Artis Svilans; NanoLund: Centre for Nanoscience; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quantum dots; Nanowire; Thermoelectric; Maximum power; Efficientcy; Carnot; Kondo effect; Fysicumarkivet A:2018:Svilans;

   Abstract : This thesis experimentally investigates the possibilities of using quantum effects in semiconductor nanostructures for engineering their thermoelectric properties. More specifically, heterostructured InAs/InP nanowires are used to create short InAs quantum dots (QDs) with electronic state structure resembling that found in atoms. READ MORE

7. 5. Index theory in geometry and physics

   Author : Magnus C H T Goffeng; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Index theory; Cyclic cohomology; Regularized index formulas; Toeplitz operators; Pseudo-differential operators; Quantum Hall effect; Toeplitz operators;

   Abstract : This thesis contains three papers in the area of index theory and its applications in geometry and mathematical physics. These papers deal with the problems of calculating the charge deficiency on the Landau levels and that of finding explicit analytic formulas for mapping degrees of Hölder continuous mappings.
