1. The black hole information paradox and holography
Master-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : Hawking theorized in 1974 that black holes emit particles as a quantum effect. It follows from this fact that a black hole that emits particles while absorbing none ends up evaporating. The process of black hole evaporation studied from semiclassical gravity violates quantum mechanics leading to serious problems. LÄS MER
2. Holographic RG-flows and the Domain-Wall/Cosmology correspondence
Master-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : In this master thesis we investigate implications of the Domain-Wall/Cosmology (DW/C) correspondence on one-point functions of holographic RG-flows. The thesis gives a detailed computation of linearized gauge-invariant Einstein equations in (d+1) dimensions while making the DW/C correspondence explicit. LÄS MER
3. Spinning Correlators at Finite Temperature
Master-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : 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. LÄS MER
4. Quantum structure of holographic black holes
Master-uppsats, KTH/FysikSammanfattning : We study a free quantum scalar field in the BTZ spacetime as a model of the AdS/CFT correspondence for black holes, and show the essential steps in computing Bogolyubov coefficients between modes on either side of the wormhole. As background, we review the BTZ geometry in standard, Kruskal and Poincaré coordinates, holographic renormalisation of the dual field theory and canonical quantisation in curved spacetime. LÄS MER
5. Domain wall solutions in the AdS/CFT correspondence
Master-uppsats, Uppsala universitet/Teoretisk fysikSammanfattning : 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.
