摘要

我们通过复朗之万方法讨论低温高密度下QCD的味数依赖性。在我们之前的工作中,复朗之万方法被确认在某些区域满足正确收敛判据,例如在83×168^3 \times 16μq/T=5.27.2\mu_{\rm q} / T = 5.2-7.2以及在163×3216^3 \times 32上使用Nf=4N_{\rm f} = 4交错费米子于β=5.7\beta = 5.7μq/T=1.69.6\mu_{\rm q} / T = 1.6-9.6。我们将此研究扩展到更现实的味情形,即使用Wilson费米子的Nf=2,2+1,3N_{\rm f} = 2, 2 + 1, 3。我们给出了复朗之万方法有效区域及夸克数的味数依赖性。
