论文摘要
Quark-Hadron的连续性具有两种风味的夸克，该夸克最近提出了与中子$^3p_2 $超流体和两种风味密集的夸克物质联系起来的HADRONIC MATESS。这个两种味道的夸克阶段由2SC冷凝物的共存和$ d $ quarks的$ p $ - 波克diquark冷凝水组成，这会引起颜色超导性和超流量。我们在此阶段对涡流进行了分类。最稳定的涡旋是我们所谓的非亚伯利亚爱丽丝弦乐，它们是其中具有非亚伯利亚颜色磁通量的超流体涡流，表现出所谓的拓扑阻塞，或者是对爱丽丝属性的非亚洲概括。我们表明，单个Abelian超级流体涡流不稳定，不稳定衰减成三个非亚伯来语爱丽丝弦。我们发现，在$ p $ - 波冷凝物的情况下，一个非阿布尔爱丽丝字符串带有真实投影空间的定向模量$ \ mathbb {r} p^2 $。我们计算非亚伯式爱丽丝弦乐器周围的Aharanov-Bohm（AB）阶段，发现2SC冷凝物和弦的定向模量必须彼此对齐，因为2SC冷凝物的AB阶段的单价值。
Quark-hadron continuity with two-flavor quarks that was proposed recently connects hadronic matter with neutron $^3P_2$ superfluidity and two-flavor dense quark matter. This two-flavor dense quark phase consists of the coexistence of the 2SC condensates and the $P$-wave diquark condensates of $d$-quarks, which gives rise to color superconductivity as well as superfluidity. We classify vortices in this phase. The most stable vortices are what we call the non-Abelian Alice strings, which are superfluid vortices with non-Abelian color magnetic fluxes therein, exhibiting so-called topological obstruction, or a non-Abelian generalization of the Alice property. We show that a single Abelian superfluid vortex is unstable against decay into three non-Abelian Alice strings. We discover that a non-Abelian Alice string carries orientational moduli of the real projective space $\mathbb{R}P^2$ corresponding to the color flux therein in the presence of the $P$-wave condensates alone. We calculate Aharanov-Bohm (AB) phases around the non-Abelian Alice string, and find that the 2SC condensates and string's orientational moduli must be aligned with each other because of single-valuedness of the AB phases of the 2SC condensates.
