论文摘要
我们分析了NAMBU - JONA-LASINIO模型在寒冷和致密区域的手性相变，开发了各向异性张量重量规定组算法的Grassmann版本。该模型是通过kogut- susskind fermion动作制定的。我们使用手性冷凝物作为订单参数来研究手性对称性的恢复。在大量的$ V = 1024^4 $上，在消失的温度下，在消失的温度下，在消失的温度下清楚地观察到一阶手性相变。我们还提出了状态方程的结果。
We analyze the chiral phase transition of the Nambu--Jona-Lasinio model in the cold and dense region on the lattice developing the Grassmann version of the anisotropic tensor renormalization group algorithm. The model is formulated with the Kogut--Susskind fermion action. We use the chiral condensate as an order parameter to investigate the restoration of the chiral symmetry. The first-order chiral phase transition is clearly observed in the dense region at vanishing temperature with $μ/T\sim O(10^3)$ on a large volume of $V=1024^4$. We also present the results for the equation of state.
