6. Structure of Deformed Proton-rich Nuclei Studied by Beta-decay
Sammanfattning : Nuclear structure is studied using beta-decay reactions as a probe and focusing on medium-heavy proton-rich nuclei. One of the included articles is a systematic study covering a major part of the nuclear chart, especially searching for nuclei which may be sensitive to sub-MeV neutrinos... LÄS MER
7. Phase transitions in novel superfluids and systems with correlated disorder
Sammanfattning : Condensed matter systems undergoing phase transitions rarely allow exact solutions. The presence of disorder renders the situation even worse but collective Monte Carlo methods and parallel algorithms allow numerical descriptions. LÄS MER
8. Structure formation, phase transitions and drag interactions in multicomponent superconductors and superfluids
Sammanfattning : Superconductivity and superfluidity are some of the most funda-mental and important phenomena of modern physics. However, muchtheoretical work for such systems so far has been restricted to the one-component case. LÄS MER
9. A Matter of Disorder : Monte Carlo Simulations of Phase Transitions in Strongly Disordered Systems
Sammanfattning : Phase transitions and their critical scaling properties, especially in systems with disorder, are important both for our theoretical understanding of our environment, but also for their practical use in applications and materials in our everyday life. This thesis presents results from finite size scaling analysis of critical phenomena in systems with disorder, using high-precision Monte Carlo simulations and state of the art numerical methods.

10. Multicomponent superconductivity : Vortex matter and phase transitions
Sammanfattning : The topic of this thesis is vortex-physics in multi component Ginzburg- Landau models. These models describe a newly discovered class of super- conductors with multiple superconducting gaps, and possess many properties that set them apart from single component models. LÄS MER
