Ladder operators of the de Sitter algebra
Manizheh Botshekananfard, Elif Büşra Güraksın, Gizem Şengör
We identify raising and lowering operators of the de Sitter algebra with focus on their action on states in particular in 4 spacetime dimensions. There isn't a unique solution to t…
Searching for discrete series representations at the late-time boundary of de Sitter
Gizem Şengör
The group makes an appearance both as the conformal group of Euclidean space in dimensions and as the isometry group of de Sitter spacetime in dimensions. Whi…
Hidden regimes during preheating
Gizem Şengör
The Effective Field Theory (EFT) of Preheating with scalar fields, implies three types of derivative couplings between the inflaton and the reheating field. Two of these couplings…
Non-thermal WIMPs and Primordial Black Holes
Julian Georg, Gizem Şengör, Scott Watson
Non-thermal histories for the early universe have received notable attention as they are a rich source of phenomenology, while also being well motivated by top-down approaches to b…
