  1. 1. MATTER-ANTIMATTER INTERACTIONS : The hydrogen-antihydrogen system and antiproton-matter interactions

    Författare :Henrik Stegeby; Roland Lindh; Dage Sundholm; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; antimatter; antiproton; matter-antimatter interactions; hydrogen-antihydrogen system; Kemi med inriktning mot kvantkemi; Chemistry with specialization in Quantum Chemistry;

    Sammanfattning : Ever since antiparticles were discovered their nature has been something of a mystery. They were postulated to be identical to regular particles except for having opposite charge, but this would imply that an equal amount of antiparticles and particles should have been created at the beginning of time.

  2. 2. Interacting Dirac Matter

    Författare :Saikat Banerjee; Alexander V. Balatsky; Jens Paaske; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Dirac; superconductor; magnon; interaction; Fermi liquid theory; renormalization; Physics; Fysik;

    Sammanfattning : The discovery of graphene in 2004 has led to a surge of activities focused on the theoretical and experimental studies of materials hosting linearly dispersive quasiparticles during the last decade. Rapid expansion in the list of materials having similar properties to graphene has led to the emergence of a new class of materials known as the Dirac materials. LÄS MER

  3. 3. Motives matter : Intrinsic motivation in work learning and labor market performance

    Författare :Johan Westerman; Michael Tåhlin; Stephanie Plenty; Martin Hällsten; Daniel Oesch; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Work motivation; Job mobility; Labor market inequality; Wages; On-the-job training; Sociology; sociologi;

    Sammanfattning : This dissertation examines the importance of individual work motivation for two crucial dimensions of inequality: work learning and labor market performance. The first dimension relates to learning activities at work, and the second to wage attainment and knowledge-oriented task assignment. LÄS MER

  4. 4. Media Matter : The Political Influences of the News Media

    Författare :Adam Shehata; Jesper Strömbäck; Tom Moring; Mittuniversitetet; []

  5. 5. Supersymmetric Dark Matter : aspects of sfermion coannihilations

    Författare :Mia Schelke; Joakim Edsjö; Nicolao Fornengo; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Supersymmetry; Dark Matter; Physics; Fysik;

    Sammanfattning : There is very strong evidence that ordinary matter in the Universe is outweighed by almost ten times as much so-called dark matter. Dark matter does neither emit nor absorb light and we do not know what it is. LÄS MER
