  2. 1. Electronic transitions and correlation effects : From pure elements to complex materials

    Author : Johan Jönsson; Igor A. Abrikosov; Marcus Ekholm; Sergei Dudarev; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electronic transition; solid state physics; condensed matter physics; correlation effects;

    Abstract : Macroscopic properties of real materials, such as conductivity, magneticproperties, crystal structure parameters, etc. are closely related or evendetermined by the configuration of their electrons, characterized by electronicstructure. By changing the conditions, e.g, pressure, temperature, magnetic/electric field, chemical doping, etc. READ MORE

  4. 2. Matter and damping effects in neutrino mixing and oscillations

    Author : Mattias Blennow; Tommy Ohlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Neutrino oscillations; neutrino mixing; matter effects; damping effects; the day-night effect; solar neutrinos; Teknisk fysik; Engineering physics; Teknisk fysik;

    Abstract : This thesis is devoted to the study of neutrino physics in general and the study of neutrino mixing and oscillations in particular. In the standard model of particle physics, neutrinos are massless, and as a result, they do not mix or oscillate. READ MORE

  5. 3. Interacting Dirac Matter

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

    Abstract : 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. READ MORE

  6. 4. Effects of Dark Matter in Astrophysical Systems

    Author : Stefan Clementz; Mattias Blennow; Tommy Ohlsson; Riccardo Catena; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dark matter; Self-interactions; solar capture; helioseismology; inelastic dark matter; direct detection; indirect detection; Fysik; Physics;

    Abstract : When studying astrophysical structures with sizes ranging from dwarf galaxies to galaxy clusters, it becomes clear that there are vast amounts of unobservable gravitating mass. A compelling hypothesis is that this missing mass, which we call dark matter, consists of elementary particles that can be described in the same manner as those of the standard model of particle physics.

  7. 5. Relativistic light-matter interaction

    Author : Tor Kjellsson Lindblom; Eva Lindroth; Bernard Piraux; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Time-dependent Dirac equation; Beyond dipole effects; Relativistic effects; High-Intensity laser-matter interaction; teoretisk fysik; Theoretical Physics;

    Abstract : During the past decades, the development of laser technology has produced pulses with increasingly higher peak intensities. These can now be made such that their strength rivals, and even exceeds, the atomic potential at the typical distance of an electron from the nucleus. READ MORE
