1. 1. Conformal field theory at large N

   Master-uppsats, Uppsala universitet/Teoretisk fysik

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

   Sammanfattning : 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. LÄS MER

3. 2. Anomalous Dimensions in the WF O(N) Model with a Monodromy Line Defect

   L3-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Alexander Söderberg; [2017]
   Nyckelord :Anomalous Dimensions; WF; O N Model; phi^4 theory; Monodromy Line Defect; Co-Dimension Two; 3 Dimensions; CFT; 3D; Dimensional; Conformal Field Theory; Quantum Field Theory; QFT;

   Sammanfattning : General ideas in the conformal bootstrap program are covered. Both numerical and analytical approaches to the bootstrap equation are reviewed to show how it can be manipulated in different ways. Further analytical approaches are studied for theories with defects. LÄS MER
