论文摘要
我们提出了一种在功能连续框架内计算热力学数量的方法，该框架与所采用的截断无关。作为原则的证明，我们首先将其应用于平均场近似中的Nambu-Jona-Lasinio模型。然后，我们使用该方法与从（2+1）的Quark和Gluon传播器中获得的一组截短的Dyson-Schwinger方程获得的溶液，以（2+1） - 燃烧的Landau仪表量表中的量子化量子动力学，以获得压力，熵密度，能量密度和相互作用的压力，和相互作用，并且相互作用跨越了强内部功能强度的相位图。我们还讨论了提出的方法的局限性。
We present a method to compute thermodynamic quantities within functional continuum frameworks that is independent of the employed truncation. As a proof of principle, we first apply it to a Nambu-Jona-Lasinio model in mean-field approximation. Then, we use the method with solutions obtained from a coupled set of truncated Dyson-Schwinger equations for the quark and gluon propagators of (2+1)-flavor quantum chromodynamics in Landau gauge to obtain the pressure, entropy density, energy density, and interaction measure across the phase diagram of strong-interaction matter. We also discuss the limitation of the proposed method.
