  1. 1. On the emergent relative distancebetween quantum systems

    Master-uppsats, KTH/Fysik

    Författare :Sebastian Jovancic; [2022]
    Nyckelord :;

    Sammanfattning : In an emergent spacetime framework where relative distances between quantum systemsare determined by the mutual information between the systems, an entangled pairmust be shown to have a non-zero distance even though its mutual information is maximalby virtue of being maximally entangled. This report shows that in fact an entangledpair is only maximally entangled in some degrees of freedom such as spin, and when oneintroduces other quantum degrees of freedom the mutual information is no longer maximaland so a non-zero distance can be recovered.

  3. 2. Matter-streams as sources of the Kerr metric

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Julian Boy; [2022]
    Nyckelord :General Relativity; Black holes; Physics; Kerr metric; Physics and Astronomy;

    Sammanfattning : An introduction to the thin-shell formalism and distributional approach to General Relativity is provided. The formalism is utilized to investigate possible distributions of matter that can act as a source to the Kerr metric. LÄS MER

  4. 3. 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
