• Gravitational waves from tachyonic preheating 

      Hetland, Bjarte (Masteroppgave/UIS-TN-IMN/2017;, Master thesis, 2017-06)
      Most models of the universe, which are in agreement with current observations, include some form of extremely rapid expansion of space at a very early stage. This is called cosmological inflation, or just inflation. Most ...
    • Quantum correction to inflation and curvature perturbation 

      Subedi, Sundar (Masteroppgave/UIS-TN-IMN/2015;, Master thesis, 2015-06)
      Inflation is a sudden and near exponential expansion of space in early universe. Infla- tion solved flatness problem, horizon problem and monopole problem that persisted in standard big bang cosmology. It was not only useful ...
