  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. 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

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

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

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

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, Stockholms universitet/Fysikum

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

    Sammanfattning : 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. LÄS MER
