  1. 1. Spinning Correlators at Finite Temperature

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Oscar Arandes Tejerina; [2022]
    Keywords : Conformal Field Theory; Finite Temperature; Thermal Conformal Blocks; AdS CFT; Mean Field Theory;

    Abstract : This master thesis is framed in the striking correspondence between gravity theories in Anti-de Sitter spacetime (AdS) and Conformal Field Theories (CFT). This is usually known as AdS/CFT duality and relates gravity theories in the bulk with CFTs that live in their conformal boundary. READ MORE

  3. 2. Recent Progress on the Black Hole Information Paradox

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

    Author : Eivind Hilmen Jørstad; [2021]
    Keywords : Black Holes; Hawking Radiation; Entanglement Entropy; Black Hole Information Paradox; Dilaton Gravity; Quasiparticles; Physics and Astronomy;

    Abstract : The black hole information paradox is of central importance in the study of quantum gravity. The paradox states that quantum fields surrounding a black hole behave in ways that run into conflict with the unitarity of quantum mechanical time evolution. READ MORE

  4. 3. 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.

  5. 4. Higgs inflation

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Erik Schildt; [2018]
    Keywords : inflation; Higgs inflation; nonminimal coupling; conformal transformation; Higgs cosmology; cosmology; higgs inflaton; inflaton;

    Abstract : In this project a recent model of inflation in which the Standard Model Higgs field with a nonminimal coupling to gravity takes on the role of the inflaton field is investigated. The tensor to scalar ratio, spectral index and the running of the spectral index  is calculated for a tree level analysis and compared with the Planck experiment. READ MORE

  6. 5. AdS/CFT correspondence and c-extremization

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Roberto Goranci; [2017]
    Keywords : AdS CFT; c-extremization; Super Yang-Mills; Supergravity; M5 membrane; Conformal field theory; Anomalies; superconformal CFT; 6d SCFT; black string; String theory; compactification;

    Abstract : In this project we review the method of using c-extremization and computing anomalies to obtain AdS/CFT theories. We start with a quick introduction to CFT's and AdS/CFT correspondence which gives us the tools to later understand the 2D N= (2,0) SCFT and its gravity duals in particular AdS_5xS^5 and AdS_7xS^4 compactified on Riemann surfaces. ..
