We report on the status of our QCD thermodynamics project. It is performed on the QCDOC machine at Brookhaven National Laboratory and the APEnext machine at Bielefeld University. Using a 2+1 flavor formulation of QCD at almost realistic quark masses we calculated several thermodynamical quantities. In this proceeding we show the susceptibilites of the chiral condensate and the Polyakov loop, th...

We measure the low lying eigenmodes of an overlap Dirac operator on 2–flavor staggered configurations. By comparing the eigenmode distribution to the predictions of Random Matrix Theory we test to what accuracy staggered configurations describe continuum QCD. The agreement between the numerical data and RMT implies that at our quark mass values the lattice artifacts of the staggered configurati...

Thermodynamic quantities in symmetric nuclear matter are calculated in a self-consistent T−matrix approximation at zero and finite temperatures. The internal energy is calculated from the Galitskii-Koltun’s sum rule and from the summation of the diagrams for the interaction energy. The pressure and the entropy at finite temperature are obtained from the generating functional form of the thermod...
