  1. 1. Interacting Dirac Matter

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

    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

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; relativitet; kvantmekanik; klassisk mekanik; Matematisk och allmän teoretisk fysik; massive neutrinos; fermion masses; Mathematical and general theoretical physics; self-dual fields; democratic family mixing; quantum mechanics; classical mechanics; relativity; gravitation; thermodynamics; statistical physics; statistisk fysik; termodynamik; Elementary particle physics; quantum field theory; Elementarpartikelfysik; kvantfältteori; Fysicumarkivet A:1997:Kleppe;

    Sammanfattning : This thesis deals with different types of chiral fields. The properties of fermion masses are investigated from different poits of view, both within the Standard Model and in extensions of the model. It is shown how mass matrix invariants are used to define the measurables of the quark mixing matrix as invariant functions of the mass matrices. LÄS MER

  4. 3. Higher Order Calculations for Low Energy Precision Physics

    Författare :Nils Hermansson Truedsson; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Effective Field Theory; Chiral Perturbation Theory; The Muon Anomalous Magnetic Moment; Lattice Gauge Theory; Finite Volume Effects; Fysicumarkivet A:2019:Hermansson; Effektiv fältteori; Kiral störningsräkning; Myonens anomala magnetiska moment; Gitter-gaugeteori; Ändlig-volymkorrektioner;

    Sammanfattning : This thesis concerns higher order calculations needed for precision physics in the low energy region of particlephysics. Of the four papers it contains, the first two introduce calculations at order p8 in the power countingof chiral perturbation theory, which is an effective field theory of QCD at low energies. LÄS MER
