  1. 6. Inference on Dark Matter in Effective Field Theories : From XENON1T towards XENONnT: Chiral effective field theory analysis of nuclear recoils, single electrons and uncommon background modelling

    Författare :Vasile Cristian Antochi; Jan Conrad; Björn Penning; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dark Matter; Direct Detection; Effective Field Theory; Chiral Effective Field Theory; Physics; fysik;

    Sammanfattning : Cosmological and astronomical observations show that most of the matter in the Universe is dark. This dissertation provides an overview of the dark matter evidence, and focuses on the particle dark matter hypothesis, describing possible particle candidates, concentrating on the Weakly Interactive Massive Particles (WIMPs).

  3. 7. Phase-field modeling of surface-energy driven processes

    Författare :Klara Asp Grönhagen; John Ågren; Suzana Fries; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-field method; surface energy; solute drag; solid-state sintering; multicomponent multiphase flow; wetting; liquid-phase sintering; spinodal decomposition; CALPHAD; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Surface energy plays a major role in many phenomena that are important in technological and industrial processes, for example in wetting, grain growth and sintering. In this thesis, such surface-energy driven processes are studied by means of the phase-field method. LÄS MER

  4. 8. The measurement of chemical persistence in the field by benchmarking : Theory and Experiment

    Författare :Hongyan Zou; Michael McLachlan; Keri Hornbuckle; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chemical benchmarking; persistence; half-lives; modeling; threshold benchmarking; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Persistence is one of the core criteria in chemical exposure and hazard assessment. It is often defined as the half-life for the removal of a chemical from a specified environment by transformation. Chemicals with long transformation half-lives may pose high risks for wildlife or humans and be subject to long-range transport to remote areas. LÄS MER

  5. 9. Multicomponent superconductivity : Vortex matter and phase transitions

    Författare :Johan Carlström; Egor Babaev; Leo Radzihovsky; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Ginzburg Landau; field theory; Iron pnictide;

    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

  7. 10. Linear response theory : from black hole thermalization to Weyl semimetals

    Författare :Jorge Laraña Aragón; Bo Sundborg; Edwin Langman; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Linear response theory is an incredibly powerful calculation tool. We apply this framework in quantum field theory to a variety of models originated from distinct areas in theoretical physics and for different reasons. LÄS MER
