Expert Group 1


QCD Simulations, Dynamics and Medical Physics

Expert Group 1The research covered by the expert group 1 focuses on large-scale simulations of FAIR-related physics based on transport, monte-carlo, and hydrodynamic descriptions of matter.

We study the dynamics of ultrarelativistic heavy-ion collisions with different transport- and hydrodynamics models. Here, the experts study event-by-event fluctuations, the role of multi-particle interactions, off-shell effects in the dynamics, the effects of viscosities and the QCD phase structure. Major work is being done combining the transport and hydrodynamic descriptions in a hybrid approach. This includes efforts to integrate fluctuations of the order parameters in the simulations. In the area of lattice QCD, the main issues that are investigated are the dependence of the phase transition on the fermionic formalism adopted as well as the phase structure at non-zero baryon net density. Further, lattice simulations are exploited to determine parameters of effective models of strong interaction.

Another important facet of the expert group is the expansion of supernova explosion simulations to full 3d descriptions with neutrino transport including realistic equations of state. Heavy-ion tumor radiation simulations are performed with the aim to generate a full treatment plan for clinical therapy.

On the methodological side, work is being done to improve the numerical treatment of systems of coupled partial differential equations as they occur in various simulation approaches. This includes improved implementations of multi-grid methods.

Marcus Bleicher - Leader of Expert Group 1 (ad interim)

Marcus Bleicher received his doctoral degree from Goethe University in 1999 and his Habilitation in 2007. He spent his post-doctoral years in Berkeley, USA, and in Nantes, France. In 2003 he was appointed as a Professor of Theoretical Physics at Goethe University in Frankfurt am Main.
            He is the Scientific Director of the LOEWE center “Helmholtz International Center for FAIR” (HIC for FAIR).
Professor Bleicher has been a Senior Fellow at FIAS since 2010 and has served as Member of the Board of Directors of FIAS from 2014 to 2017. Since 2017 he is the elected chair of the European COST Action THOR. His exceptional performance was honored by the Goethe University by naming Professor Bleicher an outstanding scientist (top 10%) of the University. His leadership in the field is exemplified by various highly cited publications and memberships in several advisory boards and organizing committees.
