Wenyuan Ai (member since October 2019)
My research focuses on phase transitions as well as its applications in the early universe and electroweak vacuum metastability. I am also interested in nonequilibrium quantum field theory and black hole physics.
Jamie McDonald (IISN - IISN-THEORY) (member since November 2020)

Michele Lucente (member since January 2016)
I work on extensions of the Standard Model of particle physics aimed at accounting for the observed neutrino masses and flavour mixing, the origin of the baryon asymmetry of the Universe and the nature of dark matter. I am currently developing a new computer tool (MadbaM) devoted to precision computations of the baryon asymmetry of the Universe in beyond the Standard Model realisations.

Research statement
Many properties of the cosmos that we observe today can be understood as the result of quantum processes in the hot and dense plasma that filled the universe in the first moments after the "big bang". This allows cosmologists to understand the history of the observable universe in terms of elementary particles and the fundamental interactions between them. On the other hand, the extreme conditions in the primordial plasma allow particle physicists to test their ideas in an environment that cannot be created in the laboratory. With our research, we exploit this mutual benefit to learn about both, the fundamental laws of nature and how they shaped the cosmos that we live in.
Research directions:
Cosmology and General Relativity
Theories of the fundamental interactions
Phenomenology of elementary particles

Active projects
Neutrino Masses as a Key to New Physics
Marco Drewes, Michele Lucente

We study the perspectives to probe the origin of neutrino mass with existing or near future experiments. The focus lies on low scale seesaw scenarios involving heavy right handed neutrinos. We are also interested in cosmological implications, such as leptogenesis or connections to Dark Matter.
Neutrinos in the Early Universe
Marco Drewes

We study the production and interactions of neutrinos in the primordial plasma from first principles of quantum field theory. This includes Standard Model computations such as QED corrections to Neff as well as constraints on new neutrinos species from cosmology and astrophysics.
New Paths to Hidden Sectors
Chiara Arina, Marco Drewes, Andrea Giammanco

We study the perspectives to search for new long lived particles with existing accelerator facilities. This includes searches for non-standard signatures at the LHC main detectors, fixed target experiments and searches in heavy ion collisions.
New Physics in compact stars
Marco Drewes, Jamie McDonald, Loïc Sablon

We investigate constraints on the properties of new elementary particles from the observation of compact stars.
Non-thermal Dark Matter
Marco Drewes, Jan Heisig, 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
Wenyuan Ai, 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.
Testable Baryogenesis
Marco Drewes, Yannis Georis, Michele Lucente

We study the perspectives to probe the origin of baryonic matter in the observable universe with laboratory experiments. Currently the focus lies on low scale leptogenesis scenarios. A key element of our approach lies in the description of CP violating nonequilibrium processes in the early universe from first principles of nonequilibrium quantum field theory.
