论文摘要
臭名昭著的符号问题使得在接近或低于解元阈值的温度下探测密度（BARYON密度$μ_B> 0 $）。作为解决方法，人们可以探索类似QCD的理论，例如两色QCD（QC2D），这些理论不会遭受此标志问题的困扰，但与REAL QCD非常相似。先前关于较小晶格量的研究研究了对正常物质转变的解料和颜色超流体。在这项研究中，我们查看较大的晶格量$ n_s = 24 $，以试图消除有限的体积和有限的温度效应。我们还适合大量的diquark源，以更好地允许外推到零diquark源。
The infamous sign problem makes it impossible to probe dense (baryon density $μ_B>0$) QCD at temperatures near or below the deconfinement threshold. As a workaround, one can explore QCD-like theories such as two-colour QCD (QC2D) which don't suffer from this sign problem but are qualitively similar to real QCD. Previous studies on smaller lattice volumes have investigated deconfinement and colour superfluid to normal matter transitions. In this study we look at a larger lattice volume $N_s=24$ in an attempt to disentangle finite volume and finite temperature effects. We also fit to a larger number of diquark sources to better allow for extrapolation to zero diquark source.
