    Cosmological perturbations including matter loops. A study in de Sitter 

    Fröb, Markus Benjamin (Date of defense: 2013-12-09)

    In this thesis we studied quantum effects in de Sitter space coming from the interaction of gravitons and matter. We derived the lowenergy effective action for metric perturbations which includes corrections from matter ...
