  1. 1. The black hole information paradox and holography

    University essay from Uppsala universitet/Teoretisk fysik

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

    Abstract : 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. READ MORE

  3. 2. Balancing Speed and Security: Assessing the Legislative Proposal on Instant Payments in Euro for AML/CFT Measures

    University essay from Lunds universitet/Juridiska institutionen; Lunds universitet/Juridiska fakulteten

    Author : Belinda Ólafsdóttir; [2023]
    Keywords : Law and Political Science;

    Abstract : In October 2022, the European Commission announced a legislative proposal to make instant payments in euro available to all citizens with a bank account in the EU and EEA countries. When adopting new payment technologies, it can be challenging to balance security and convenience. READ MORE

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

    University essay from Uppsala universitet/Teoretisk fysik

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

    Abstract : 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. READ MORE

  5. 4. 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

  6. 5. Quantum structure of holographic black holes

    University essay from KTH/Fysik

    Author : Elias Riedel Gårding; [2020]
    Keywords : 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;

    Abstract : 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. READ MORE
