Award ceremony



Dr. Andreas Samberg has received the Ruprecht Karls Award for outstanding scientific achievements in his PhD dissertation. The Heidelberg University Foundation honors his research on the theory of strongly coupled quantum systems performed at the University Heidelberg and at the ExtreMe Matter Institute EMMI at GSI.

Dr. Andreas Samberg has received the Ruprecht Karls Award for his doctoral thesis entitled "Applied String Theory, Hot and Cold: A Holographic View on Quark-Gluon Plasma and Superfluids". In his research work, Dr. Andreas Samberg uses methods from string theory to describe strongly interacting quantum systems in terms of weakly interacting theories of gravity in a higher-dimensional space. The principle of this holographic duality is analogous to the well-known holograms on banknotes which generate a three-dimensional picture from a flat metal film. This holographic duality is employed by Andreas Samberg for the description of the hottest and coldest forms of matter in the Universe. On the one hand, he considers the behavior of heavy quarks in the quark-gluon plasma - an extremely hot state of matter which microseconds after the Big Bang filled the whole Universe and which is now created at the LHC accelerator at CERN. He also studies this state of matter at very high densities as they will be reached in experiments at the future FAIR facility. On the other hand, he considers a phenomenon due to which fluids flow without any viscosity at low temperatures, so-called superfluidity. He discovers new aspects of the dynamics of this state of matter, in particular concerning the turbulence of vortices at strong coupling. Two-dimensional superfluids as they are investigated here will be realized in future experiments on ultra-cold quantum gases.

The thesis honored by the award was performed under the supervision of Prof. Dr. Carlo Ewerz at Heidelberg University and at the ExtreMe Matter Institute EMMI at GSI. It was supported by GSI with a fellowship in the framework of the strategic cooperation with Heidelberg University. During his thesis work, Andreas Samberg was a member of the Heidelberg Graduate School of Fundamental Physics (HGSFP) and of the Helmholtz Graduate School for Hadron and Ion Research (HGS-HIRe). Together with EMMI, the latter supported a research stay of several months at Princeton University (USA).

The Ruprecht Karls Award is endowed with 3000 Euro and is awarded by the Heidelberg University Foundation for outstanding research work by young scientists at the Ruprecht-Karls-University Heidelberg. Each year, the award honors the five best doctoral theses of all disciplines at Heidelberg University which are selected in a university-wide, multistage procedure. The award was presented in a ceremony in the Great Hall of the University Heidelberg.
