  1. 1. F-theory on six-dimensional symmetric toroidal orbifolds

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Finn Bjarne Kohl; [2021]
    Nyckelord :F-theory; orbifolds; String Theory; String Phenomenology; roto-translations; six-dimensional; F-Theorie; Orbifaltigkeiten; String Theorie; String Phenomenologie; Roto-Translationen; sechs-dimensional;

    Sammanfattning : In this thesis, compactifications of F-theory on six dimensional symmetric toroidalorbifolds are explored. These orbifold geometries have been mathematically classified and it is natural to ask what the physical implications of string theorycompactifications on those geometries are. LÄS MER

  3. 2. Reduction Mechanics of The Cosmological Constant

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Martin Sandström; [2018]
    Nyckelord :gravity; branes; adm;

    Sammanfattning : The quantum creation of membranes by a totally antisymmetric tensor and gravitational fields is considered in arbitrary space-time dimensions. The creation process is described by instanton tunneling. LÄS MER

  4. 3. Warped D-Brane Inflation and Toroidal Compactifications

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Marcus Stålhammar; [2017]
    Nyckelord :;

    Sammanfattning : We set out on the ambitious journey to fuse inflation and string theory. We first give a somewhat extensive, yet free from the most complicated details, review of string inflation, discussing concepts as flux compactifications, moduli stabilization, the η-problem and reheating.

  5. 4. Counting Black Hole Microstates in String Theory

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Jorge Laraña Aragón; [2017]
    Nyckelord :;

    Sammanfattning : In this project, we explore the area of black holes in String Theory. String Theory has had several successes in describing properties of black holes. LÄS MER
