  1. 1. A kernel function approach to exact solutions of Calogero-Moser-Sutherland type models

    Författare :Farrokh Atai; Edwin Langmann; Hjalmar Rosengren; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kernel functions; Calogero-Moser-Sutherland models; Ruijsenaarsvan Diejen models; Elliptic functions; Exact solutions; Source Identities; Chalykh- Feigin-Sergeev-Veselov type deformations; non-stationary Heun equation; Physics; Fysik;

    Sammanfattning : This Doctoral thesis gives an introduction to the concept of kernel functionsand their signicance in the theory of special functions. Of particularinterest is the use of kernel function methods for constructing exact solutionsof Schrodinger type equations, in one spatial dimension, with interactions governedby elliptic functions.

  3. 2. Topology Meets Frustration : Exact Solutions for Topological Surface States on Geometrically Frustrated Lattices

    Författare :Flore Kiki Kunst; Emil Bergholtz; Jack Lidmar; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Topology; boundary states; surface states; edge states; Chern insulator; Weyl semimetal; Theoretical Physics; teoretisk fysik;

    Sammanfattning : One of the main features of topological phases is the presence of robust boundary states that are protected by a topological invariant. Famous examples of such states are the chiral edge states of a Chern insulator, the helical edge states of a two-dimensional Z2 insulator, and the Fermi arcs of Weyl semimetals. LÄS MER

  5. 4. Theoretical and Phenomenological Studies of Neutrino Physics

    Författare :Mattias Blennow; Tommy Ohlsson; Eligio Lisi; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neutrino mass; neutrino mixing; neutrino oscillations; matter effects; non-standard effects; the day-night effect; solar neutrinos; accelerator neutrinos; exact solutions; three-flavor effects; large density; neutrino decay; neutrino decoherence; neutrino absorption; non-standard neutrino interactions; seesaw mechanism; stability criteria; leptogenesis; Physics; Fysik;

    Sammanfattning : This thesis is devoted to the theory and phenomenology of neutrino physics. While the standard model of particle physics has been extremely successful, it fails to account for massive neutrinos, which are necessary to describe the observations of neutrino oscillations made by several different experiments.

  7. 5. Interactions in aqueous salt solutions : Atomistic modelling versus experiment

    Författare :Vidar Aspelin; Beräkningskemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; statistisk mekanik; molekylär modellering; MD simuleringar; MC simuleringar; statistical mechanics; molecular simulation; MD simulations; MC simulations; Kirkwood-Buff theory; Hofmeister series;

    Sammanfattning : The research in this thesis investigates how atoms and molecules constituting aqueous salt solutions interact using computational approaches, namely Monte Carlo simulations and molecular dynamics simulations. In the first paper, an atomistic model was developed for aqueous solutions of sodium thiocyanate and potassium thiocyanate (NaSCN and KSCN). LÄS MER
