  1. 1. A Primer to Categorical Symmetries and Their Application to QCD in Two Dimensions

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Rikard Olofsson; [2021]
    Nyckelord :category theory; fusion category; topological defect lines; rational conformal field theory; Wess Zumino Witten-model; QCD;

    Sammanfattning : We introduce the formalism of categorical symmetries, and examine how these appear in quantum field theories. We discuss rational conformal field theories and their Verlinde lines, with the critical Ising model as an example. We introduce Wess Zumino Witten models and affine Lie algebras. An algorithm for the fusion rules is presented. LÄS MER

  3. 2. Equivalence of the sine-Gordon Model and the Massive Thirring Model: Derivations and Application

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Erik Linnér; [2017]
    Nyckelord :sine-Gordon model; Thirring model; Schwinger model; Bosonization; Physics and Astronomy;

    Sammanfattning : The equivalence of the sine-Gordon model and the massive Thirring model, (1+1) dimensional theories of a single scalar field respectively a single Dirac field, is derived by two alternative approaches. The equivalence is derived by a comparison of the perturbation expansions of the correlation functions of the theories around the corresponding massless theories. LÄS MER
