Wenyuan Ai (UCL-FSR - D.31500.030) (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.
Drazen Glavan (member since January 2019)
My research interests lie in the overlap of non-equilibrium quantum field theory and cosmology. In particular, my research focuses on quantum loop effects in primordial inflation, perturbative quantum gravity, and warm inflation, both from the formal and phenomenological approach.
Richard Ruiz (UCL-FSR) (member since October 2018)
I am a high energy physicist and collider theorist. My primary research focuses on understanding the origin of tiny, nonzero neutrino masses and tests of neutrino mass models (Seesaw models) at collider experiments, such as the Large Hadron Collider. This includes extended gauge sectors (LR-Symmetric, GUT models), scalar sectors (SU(2)L doublets and triplets), and fermionic sectors (SU(2)L singlets and triplets). I have a particular interest in collider signatures involving initial-state electroweak vector bosons (vector boson fusion/scattering) and the impact of (resummed) QCD corrections on (new physics) collider processes. This includes resummation in the context of perturbative QCD and SCET.

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.

Active projects
Neutrino Masses as a Key to New Physics
Marco Drewes, Jan Hajer, Philipp Klose

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
Gilles Buldgen, Marco Drewes, Philipp Klose

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, Jan Hajer, Philipp Klose

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.
Scalar Fields in the Early Universe
Wenyuan Ai, Gilles Buldgen, Marco Drewes, Drazen Glavan, Philipp Klose, Lei Ming

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, Philipp Klose

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.
