  1. 1. The Ratio of Reality : A study of the gyromagnetic ratio in theories ranging from classical mechanics to string theory

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Daniel Nilsson; [2021]
    Keywords : Quantum field theory ; String theory ; Dirac equation ; Dirac theory ; Dirac; gyromagnetic; ratio; g-factor; Kvantfältsteori; strängteori; Dirac; g-factor; gyrmagnetisk kvot ;

    Abstract : In this project a theoretical study of the so called gyromagnetic ratio was done by investigating classical mechanics, Dirac theory and string theory. The gyromagnetic ratio is a constant term appearing in the coupling between angular momentum and magnetic moment for a particle. READ MORE

  3. 2. Model building on gCICYs

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Davide Passaro; [2020]
    Keywords : Mathematical Physics; Geometry; Calabi Yau; Complete Intersection Calabi Yau; Generalized Complete Intersection Calabi Yau;

    Abstract : Prompted by the success of heterotic line bundle model building on Complete Intersection Calabi Yau (CICY) manifolds and the new developments regarding a generalization thereof, I analyze the possibility of model building on generalized CICY (gCICY) manifolds.  Ultimately this is realized on two examples of gCICYs, one of which topologically equivalent to a CICY and one inequivalent to any previously studied examples.

  4. 3. Conformal field theory at large N

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Nadia Flodgren; [2019]
    Keywords : Conformal field theory; conformal bootstrap; large N; anti-de Sitter; anomalous dimension; AdS CFT correspondence;

    Abstract : The conformal bootstrap method is a non-perturbative method that uses the symmetry in a conformal field theory to constrain and solve for the observables in the theory. We consider a conformal field theory with the symmetry group SU(N) and four general scalar fields as the only low dimensional operators. READ MORE

  5. 4. Counting Black Hole Microstates in String Theory

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Jorge Laraña Aragón; [2017]
    Keywords : ;

    Abstract : In this project, we explore the area of black holes in String Theory. String Theory has had several successes in describing properties of black holes. READ MORE

  6. 5. An introduction to Krein strings

    University essay from Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Author : Tien Truong; [2017]
    Keywords : Spectral theory; Krein strings; vibrating strings; non-constant density; Mathematics and Statistics;

    Abstract : Krein strings appear in the study of the motion of a vibrating string where an irregular density is allowed. This thesis presents the theory from the perspective of integral equations and operator theory. READ MORE
