AbstractAbstract
[en] Full text: The quark propagator is calculated in the Nambu-Jona-Lasinio (NJL) model in a self-consistent 1/Nc expansion at next-to-leading order. The chiral quark condensate and its dependence on temperature and chemical potential is calculated directly and compared with mean field results. By using the Maximum-Entropy-Method (MEM) spectral functions are determined from the Euclidean propagators. We find a second order phase transition for the quark condensate at finite temperature whereas the critical temperature is reduced in comparison with mean field results. (author)
