Revisiting zero modes and cluster decomposition at the late-time boundary of de Sitter
Murat Onem, Gizem Sengor
We revisit the literature on locality on de Sitter with the goal to organize the main results with respect to the representation theory of the isometry group of four dimensional de…
The de Sitter group and its presence at the late-time boundary
Gizem Sengor
Our main goal here is to provide an introduction on some of the well established properties of the representation theory of SO(d+1,1), for those considering to think on physical pr…
Principal and complementary series representations at the late-time boundary of de Sitter
Gizem Sengor, Constantinos Skordis
We demonstrate how free massive scalar fields in the set up that usually appears in early universe inflationary studies, correspond to the principal series and complementary series…
Cosmological Perturbations in the Early Universe
Gizem Sengor
One essence in capturing the history of primordial fluctuations that arise during inflation and eventually lead to formation of large scale structures in the universe, relies on qu…
A Model Independent Approach to (p)Reheating
Ogan Özsoy, Gizem Sengor, Kuver Sinha +1
In this note we propose a model independent framework for inflationary (p)reheating. Our approach is analogous to the Effective Field Theory of Inflation, however here the inflaton…
A five dimensional model with a fifth dimension as fundamental as time in terms of a cosmological approach
Gizem Sengor, Metin Arik
In five dimensional cosmological models, the convention is to include the fifth dimension in a way similar to the other space dimensions. In this work we attempt to introduce the f…
