论文摘要
我们使用晶格QCD的直接模拟在物理夸克质量下的晶格QCD进行直接模拟，计算零QCD的异种状态不对称QCD的方程。除了压力和痕量异常及其对连续性极限的行为外，我们还将特别讨论声音速度的提取。此外，我们讨论了通过泰勒膨胀将EOS扩展到小型非零BARYON化学电位的第一步。
We compute the equation of state of isospin asymmetric QCD at zero and non-zero temperatures using direct simulations of lattice QCD with three dynamical flavors at physical quark masses. In addition to the pressure and the trace anomaly and their behavior towards the continuum limit, we will particularly discuss the extraction of the speed of sound. Furthermore, we discuss first steps towards the extension of the EoS to small non-zero baryon chemical potentials via Taylor expansion.
