I have been accepted for a position in Jülich Forschungzentrum in the Pedestrian Dynamics group. I will be part of the Hermes project. The Hermes project is developing an evacuation system to assist in the evacuation of mass events. A test system will be installed in the LTU Arena in Düsseldorf in 2011.
I am responsible for developing and applying methods for the analysis of experiemental data and for developing new models. |

Our paper on the spatial string tension has been accepted for publication in Physical Review D, it can be found here.
In the paper we calculate the spatial string tension in (2+1) flavor QCD with physical strange quark mass and almost physical light quark masses using lattices with temporal extent Nt=4,6 and 8. We compare our results on the spatial string tension with predictions of dimensionally reduced QCD. This suggests that also in the presence of light dynamical quarks dimensional reduction works well down to temperatures 1.5Tc. |

My proceedings from the Lattice 2007 conference are now available here
The paper contains preliminary results for the spatial string tension for 3+1 dimensional QCD. The comparison with 3 dimensional pure gauge theory and dimensionally reduced effective theories is shown.
Data for Nt= 8 is has now been analysed and the systematic errors are being quantified. The full paper should be available shortly. |

Soon I will be heading to Lattice 2007 in Regensburg. I will be presenting a talk in the nonzero temperature and density parallel session titled "The spatial string tension and dimensional reduction in QCD" for the RBC Bielefeld Collaboration.
The spatial string tension for 3+1 dimensional QCD at finite temperature is measured. The gauge configurations were generated with two light and one heavier strange quark on lattices of size 163 4 and 243 6. This spatial string tension is compared with the string tension of the 3 dimensional pure gauge theory together with the temperature dependent 2-loop running coupling. Further comparison is made with predictions from dimensionally reduced effective theories. |

At the beginning of January 2007 I defended my DPhil thesis in Oxford. My examiners were Professor Frank Close from Oxford and Dr. Biagio Lucini from Swansea. The defense took about one hour and three quarters after which I was left with some minor corrections to clear up before returning to Bielefeld. |
