  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. 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

  4. 3. 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

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

    University essay from Stockholms universitet/Fysikum

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

    Abstract : 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. READ MORE
