  1. 1. One-dimensional theory of the quantum Hall system

    Författare :Emil Johansson Bergholtz; Anders Karlhede; Nicholas Read; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fractional quantum Hall effect; thin torus; spin chains; conformal field theory; strong correlations; non-abelian states; Condensed matter physics; Kondenserade materiens fysik; Theoretical Physics; teoretisk fysik;

    Sammanfattning : The quantum Hall (QH) system---cold electrons in two dimensions in a perpendicular magnetic field---is a striking example of a system where unexpected phenomena emerge at low energies. The low-energy physics of this system is effectively one-dimensional due to the magnetic field. LÄS MER

  3. 2. Energy Efficiency in Machine Learning : Approaches to Sustainable Data Stream Mining

    Författare :Eva García Martín; Håkan Grahn; Veselka Boeva; Emiliano Casalicchio; Jesse Read; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; machine learning; energy efficiency; data stream mining; green machine learning; edge computing; Computer Science; Datavetenskap;

    Sammanfattning : Energy efficiency in machine learning explores how to build machine learning algorithms and models with low computational and power requirements. Although energy consumption is starting to gain interest in the field of machine learning, still the majority of solutions focus on obtaining the highest predictive accuracy, without a clear focus on sustainability.

  4. 3. Dark Matter searches targeting Dwarf Spheroidal Galaxies with the Fermi Large Area Telescope

    Författare :Maja Garde Lindholm; Jan Conrad; Alexander L. Read; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dark matter; Fermi-LAT; dwarf spheroidal galaxies; fysik; Physics;

    Sammanfattning : In this thesis I present our recent work on gamma-ray searches for dark matter with the Fermi Large Area Telescope (Fermi-LAT). We have targeted dwarf spheroidal galaxies since they are very dark matter dominated systems, and we have developed a novel joint likelihood method to combine the observations of a set of targets.

  7. 5. The mobility of natural uranium at Forsmark, Sweden, through geologic time

    Författare :Lindsay Krall; Carl-Magnus Mörth; David Read; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; uranium; radium; mineralogy; geochronology; submarine groundwater discharge; spent nuclear fuel; geochemical modelling; Geology; geologi;

    Sammanfattning : In this thesis, the response of uranium minerals and poorly crystalline phases to changes in geochemical conditions through geological time has been assessed in order to understand the mobility of natural uranium in the fracture network of a proposed site for a spent nuclear fuel repository in Forsmark, Sweden. Identification and characterization of solid phase uranium have been performed through electron microprobe analysis and optical petrography (Article I). LÄS MER
