About my research work
I started working at the Institute for Theoretical Physics in January 2002. My work is centered around describing properties of the quark gluon plasma theoretically. Currently I deal with the so-called large-Nf limit of QCD, in which exact calculations are possible. This serves as a testing ground for other, more realistic models of QCD descriptions like 2PI, HTL perturbation theory, and so on. The next aim is to study the Non-Fermi-Liquid behaviour of this theory more carefully.
Even if supercolliders nowadays provide enough energy to produce the quark-gluon-plasma, it's actual physical properties are very difficult to calculate. The theoretical framework is QCD (Quantum chromo dynamics) at very high temperature. Early attemts to calculate the pressure and entropy of the then hypothetical quark-gluon-plasma in the 1960s resulted in expansions in the coupling g that didn't seem to converge and thus didn't produce useful results. Theoretical advance was possible by the resummed perturbation theory in the 1990s. These calculations give quite reasonable expansions already at leading order (LO) in the coupling constant. The mathematics involved is pretty extensive so that a full next-to-leading order (NLO) calculation has not been fully performed yet. Part of my current work is to try to fill missing parts of the NLO calculation first published by Blaizot, Iancu and Rebhan in 2000.
My supervisor is Dr. Anton Rebhan, one of the authors mentioned above. I am very happy to work together with Paul Romatschke who also works on his dissertation on a similar project as me under the same supervisor. We have a lot of fruitful discussions about our work. I persue my doctoral degree at the Vienna University of Technology, Particle Physics Group. My work is supported by the "Fonds zur Förderung der wissenschaftlichen Forschung (FWF)" with the project "Ultraheiße Quantenfeldtheorien", Projekt-Nr.: P14632-TPH.
Do you produce the Quark Gluon Plasma?
No. My work is of theoretical nature. I produce lots of pages full of hand-written mathematical formulae. Furthermore I write computer programs in the MathematicaTM programming environment for both symbolic and numeric calculations.
Do you have any publications?
Yes! =) Please look at the top of this page. You might also want to have a look at my diploma thesis.
