研究了平均场以外的Polyakov扩展夸克-介子模型。这是迈向完全动态QCD计算的重要一步。包括了量子涨落对物质扇区的影响以及物质涨落对QCD杨-米尔斯扇区的反作用。手性和限制-解除限制交叉/相变线和一个可能的关键终点的位置上的结果。此外，热力学量，如压力和夸克密度进行了讨论。
The Polyakov-extended quark–meson model (PQM) is investigated beyond mean-field. This represents an important step towards a fully dynamical QCD computation. Both the quantum fluctuations to the matter sector and the back-reaction of the matter fluctuations to the QCD Yang–Mills sector are included. Results on the chiral and confinement–deconfinement crossover/phase transition lines and the location of a possible critical endpoint are presented. Moreover, thermodynamic quantities such as the pressure and the quark density are discussed.
