  1. 1. The black hole information paradox and holography

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Ona Mola Bertran; [2023]
    Nyckelord :information paradox; semiclassical physics; holography; AdS CFT correspondence; island formula; entanglement entropy;

    Sammanfattning : 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

  3. 2. Holographic RG-flows and the Domain-Wall/Cosmology correspondence

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Jean-François Vaduret; [2022]
    Nyckelord :holography; cosmology; domain-wall; AdS; CFT; correspondence;

    Sammanfattning : 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

  4. 3. Spinning Correlators at Finite Temperature

    Master-uppsats, Uppsala universitet/Teoretisk fysik

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

    Sammanfattning : 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

  5. 4. Online Ads: The influence of color cues on sensory expectation : An expectation-based approach to explain the cross- modal influence of color cues in online ads

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Maxime Lindholm; Sofia Svensson; [2021]
    Nyckelord :Cross-modal correspondence; sensory expectation; perception; color psychology;

    Sammanfattning : The purpose of this thesis is to contribute to new insights into how businesses can utilize color cues as a multisensory tool in online ads to evoke positive sensory expectations. An expectation-based approach was used to examine the cross-modal influence of warm relative to cold colored cues. The theory chapter starts with sensory marketing. LÄS MER

  7. 5. Quantum structure of holographic black holes

    Master-uppsats, KTH/Fysik

    Författare :Elias Riedel Gårding; [2020]
    Nyckelord :BTZ spacetime; black hole; wormhole; AdS CFT; holographic renormalisation; analytic continuation; Bogolyubov transformation; QFT in curved spacetime; BTZ-rumtid; svart hål; maskhål; AdS CFT; holografisk renormering; analytisk fortsättning; Bogolyubov-transformation; kvanfältsteori i krökt rumtid;

    Sammanfattning : 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
