Research Group of Jan Steinheimer-Froschauer
The research group focuses on developing and applying computational techniques to explore the properties and interactions of strongly interacting matter, such as hadrons, quarks and gluons in dense QCD matter and the quark-gluon plasma. The research involves using large-scale simulations and modeling, as well as machine and deep-learning methods, to study the behavior of matter under extreme conditions, such as those found in heavy-ion collisions and inside compact astrophysical objects like neutron stars. The group also works on developing new algorithms and software tools to understand the equation of state of quantum chromodynamics, the theory that describes the interactions of quarks and gluons. Overall, the research group's goal is to advance our understanding of the fundamental properties of matter and the evolution of the universe.

Dense matter in heavy ion collisions and neutron stars
In this project, we study the properties of dense elementary matter as described by the theory of the strong interaction QCD. Experimentally this form of matter can be created in relativistic heavy ion collisions at large-scale collider experiments, e.g. at the LHC@CERN, RHIC@Brookhaven Lab and FAIR@GSI as well as in the most compact objects we know to exist, neutron stars. Our group develops numerical methods and algorithms to describe the dynamical evolution of such heavy ion collisions with either transport theory or fluid dynamics. As such, the group is part of the UrQMD project (https://urqmd.org/). An important input of these simulations is the equation of state of QCD which is related to the microscopic interactions of elementary matter. In order to study this equation of state in the dynamical simulations we also provide numerical solutions of an effective chiral mean field model (CMF) based on state-of-the-art knowledge of QCD phenomenology.
Deep- and machine learning methods for data analysis in heavy ion reactions
In this research project (started in collaboration with Dr. Kai Zhou and Prof. Horst Stöcker) we aim at developing new methods and technologies based on machine- and deep-learning techniques to extract physical information from the wealth of data that is accumulated in modern day high-energy collider experiments. The research in this project was, in part, funded by a grant of the Samson AG and the BMBF through the ErUM-data pilot project.
