I am a project leader at the Institute of Physics, working on the Lise Meitner project "Spectral properties of strong-interaction matter" funded by the FWF.

This project aims at the study of strong-interaction matter, as described by Quantum Chromodynamics (QCD), at finite temperature and density. Such extreme states of matter for example appear in the early Universe, the interior of neutron stars, or in relativistic heavy-ion collisions. In particular, real-time quantities like spectral functions and transport coefficients will be investigated with a focus on the connection to chiral symmetry. The theoretical framework to be used is the Functional Renormalization Group (FRG) which is a powerful non-perturbative continuum framework and well suited to describe phase transitions since it properly includes the effects from quantum and thermal fluctuations.

The research questions to be addressed are:

• What are the spectral properties of strong-interaction matter in various regimes of the QCD phase diagram?
• How are changes in the spectral functions of strong-interaction matter related to changes in the underlying symmetries, in particular chiral symmetry?
• What are the transport properties of strong-interaction matter in different regimes of the phase diagram?
