论文摘要
我们研究两种颜色晶格QCD（QC $ _2 $ d），在$ 40^4 $上，带有两种交错的费米子和$ 32^4 $ lattices，带有晶格间距$ a = 0.048 $ a = 0.048 $〜fm，在夸克化学范围的范围内，Quark Chemical Extigent $μ_Q$。我们的重点是该理论中的监禁终止过渡。因此，我们从威尔逊回路中计算出弦张力，并从polyakov循环中计算出静态夸克自由能。我们发现，在$μ_q\ $ 800-1000 $ MEV范围内发现的解元过渡转变为更高的值。与较早的研究相比，这种转变归因于模拟中使用的晶格间距的减小。
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 $μ_q \approx 800 - 1000$ 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.
