1. 1. When Braneworlds Collide

   Master-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Toivo Tuma Niemi; [2021]
   Nyckelord :physics; cosmology; parallel universe; dark energy; inflation; braneworlds; D brane;

   Sammanfattning : This project is an investigation of a cosmological model consisting of a five dimensional AdS-vacuum with a flux. By discharges in the flux, four dimensional bubbles can nucleate in the vacuum and collide with each other while expanding. Our observable universe is considered to be localized on the membrane of such a bubble. LÄS MER

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

   Master-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Marcus Stålhammar; [2017]

   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.
