在40 4和32 4格点上研究了格点间距a = 0的双色格点QCD（QC 2 D）. 048 fm在夸克化学势μ q的宽范围内。我们的重点是这个理论中的确认-解除转换。因此，我们计算弦张力的威尔逊圈和静态夸克自由能的波利亚科夫圈。我们发现，在µ q ≈ 800 - 1000 MeV范围内较早发现的去束缚跃迁转移到更高的值。这种转变是由于在我们的模拟中使用的晶格间距与早期的研究相比，减少。
We study two colors lattice QCD (QC 2 D) with two flavors of staggered fermions on 40 4 and 32 4 lattices with lattice spacing a = 0 . 048 fm in the wide range of the quark chemical potential µ q . Our focus is on the confinement-deconfinement transition in this theory. Thus we compute the string tension from the Wilson loops and the static quark free energy from the Polyakov loops. We find that the deconfinement transition found earlier in the range µ q ≈ 800 − 1000 MeV is shifted to higher values. This shift is attributed to decreasing of the lattice spacing used in our simulations in comparison with the earlier study.
