论文摘要
在本文中，我们使用手性扰动理论中的模型无关分析在零温度和有限的同胞化学电位（$μ_i$）下考虑两种量子QCD。我们在零和非零的piONIC源处计算有效的电势，手性冷凝物和PION冷凝物。我们比较了手性冷凝物的有限拓扑源结果和呈pion冷凝物与最近的（2+1） - 含有晶格QCD结果，并发现它们非常一致。
In this paper, we consider two-flavor QCD at zero temperature and finite isospin chemical potential ($μ_I$) using a model-independent analysis within chiral perturbation theory at next-to-leading order. We calculate the effective potential, the chiral condensate and the pion condensate in the pion-condensed phase at both zero and nonzero pionic source. We compare our finite pionic source results for the chiral condensate and the pion condensate with recent (2+1)-flavor lattice QCD results and find that they are in excellent agreement.
