  1. 1. The 2+1 Lorentz Group and Its Representations

    University essay from Stockholms universitet/Fysikum

    Author : Klas Sjöstedt; [2020]
    Keywords : The Lorentz group; representation theory; anti-de Sitter space; relativity; Lorentzgruppen; representationsteori; anti-de Sitter-rum; relativitet;

    Abstract : The Lorentz group is a symmetry group on Minkowski space, and as such is central to studying the geometry of this and related spaces. The group therefore shows up also from physical considerations, such as trying to formulate quantum physics in anti-de Sitter space. READ MORE

  3. 2. Domain wall solutions in the AdS/CFT correspondence

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Eduardo Mateos González; [2020]
    Keywords : AdS CFT correspondence; BW QFT correspondence;

    Abstract : In this thesis we study a particular realization of the Domain wall/Quantum Field Theory correspondence, a modification of the Anti de-Sitter/Conformal Field Theory correspondence that is used to study deformations of a Conformal Field Theory. In theQuantum gravity side of the duality we analyze a N = 1 gauged supergravity theory in 7 dimensions which presents two different Anti de-Sitter vacua, one of which preserves the full supersymmetry and one that breaks half of the supercharges.

  4. 3. Scalar Theory as an example of AdS/QFT

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Erik Gustafsson; [2014]
    Keywords : AdS; QFT; Scalar Theory; AdS correspondence; Physics and Astronomy;

    Abstract : We take a look at the properties of scalar fields in anti--de--Sitter space in five dimensions. More specifically we define bulk--to--boundary and bulk--to--bulk propagators for a five--dimensional scalar field and use these to calculate four--point functions. READ MORE

  5. 4. Vector Meson Masses in AdS/QCD

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Douglas Svensson Seth; [2013]
    Keywords : Theoretical particle physics; anti-de Sitter space; quantum chromodynamics; meson masses; Witten diagrams.; Physics and Astronomy;

    Abstract : We study the anti-de Sitter/conformal field theory correspondence (AdS/CFT correspondence) and investigate in a scalar model how n point functions can be calculated through functional derivatives and how they can be obtained with the use of Witten diagrams instead. We also study a previous anti-de Sitter/quantum chromodynamics (AdS/QCD) model where the mass of the phi meson has not been considered. READ MORE
