  1. 1. Electron Transport and Collective Modes in Fermi and non-Fermi Liquids

    Författare :Eric Nilsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Today’s novel materials can display many interesting phases. Two-dimensional materials with strong electron-electron interactions allow the electrons to enter a hydrodynamic regime at intermediate temperatures. LÄS MER

  3. 2. Many-body Problems in the Theory of Stellar Collapse and Neutron Stars

    Författare :Emma Olsson; Bengt Gustafsson; Christopher Pethick; Bengt Friman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; neutron stars; core-collapse supernovae; response functions; Fermi liquids; nuclear matter; neutrino interactions; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik;

    Sammanfattning : When modelling the collapse of massive stars leading to supernova explosions and the cooling of neutron stars, understanding the microphysical processes, such as the interaction of neutrinos within a dense medium are of vital importance. The interaction of neutrinos with nucleons (neutrons and protons) is altered by the presence of the medium, compared to the same process with free nucleons. LÄS MER

  4. 3. Antiferromagnets and Luttinger Liquids: Two Strongly Correlated Systems

    Författare :Ann Mattsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Strongly correlated systems show a variety of intriguing properties and have been extensively studied over the years. In this thesis two strongly correlated systems are discussed: the two-dimensional antiferromagnet and the Luttinger liquid. The Luttinger liquid has attracted much interest as a paradigm of non-Fermi liquid behavior. LÄS MER

  5. 4. Correlations in low-dimensional quantum many-particle systems

    Författare :Erik Eriksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns correlation effects in quantum many-particle systems in one and two dimensions. Such systems show many exotic non-Fermi liquid phenomena, which can be treated analytically using non-perturbative field-theory methods. LÄS MER

  7. 5. Strongly Correlated Moiré Materials

    Författare :Ahmed Abouelkomsan; Emil Bergholtz; Vladimir Juričić; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Sammanfattning : Recent advances in materials science have established Moiré materials as a new highly tunable and versatile form of quantum matter. When two dimensional atomic layers are brought into proximity, a tiny relative twist or a slight lattice mismatch produces Moiré patterns manifested in a superlattice structure with a lattice constant that is much larger than the lattice constants of the constituent layers.
