1. 1. Embedding inflation in string theory

   Master-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Kevin Björk; [2019]
   Nyckelord :inflation; string theory; racetrack; uplift; slow-roll; Kähler; moduli; modulus; manifold; Calabi-Yau;

   Sammanfattning : We introduce slow-roll inflation in string theory on both a conceptual level and a detailed one. In order to do this we first briefly review important concepts of inflation and string theory. LÄS MER

3. 2. Higgs inflation

   Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Erik Schildt; [2018]
   Nyckelord :inflation; Higgs inflation; nonminimal coupling; conformal transformation; Higgs cosmology; cosmology; higgs inflaton; inflaton;

   Sammanfattning : In this project a recent model of inflation in which the Standard Model Higgs field with a nonminimal coupling to gravity takes on the role of the inflaton field is investigated. The tensor to scalar ratio, spectral index and the running of the spectral index  is calculated for a tree level analysis and compared with the Planck experiment. LÄS MER
