Active projects
Non-thermal Dark Matter
Marco Drewes, Yuanzhen Li, Valentin Weber

We study the production of Dark Matter from non-thermal initial states in the early universe, e.g., in freeze-in scenarios. A focus of the project lies in the computation of thermal corrections.
Scalar Fields in the Early Universe
Marco Drewes

We study the nonequilibrium dynamics of scalar fields in the early universe in the framework of the Schwinger-Keldysh formalism. We are interested in several applications, including inflation, reheating, Dark Matter production and the fate of the Higgs field in the early universe.
