1. 1. Gravitational Waves in Bimetric Gravity

   Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Erik Schildt; [2022]
   Nyckelord :;

   Sammanfattning : Understanding the cause of the accelerated expansion of the Universe is one of the most pressing issues in modern cosmology. An alternative to the LambdaCDM-model is bimetric gravity which is an extension of Einstein's theory of general relativity. 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
