爱丽丝和Boojums都是刘易斯卡罗尔创造的代表性人物。我们表明，他们可能满足旋转中子星的核心。最近对夸克-强子连续性的研究表明，中子超流物质可以在高密度下与双味对称夸克物质光滑连接。我们研究如何可以保持在涡流的存在。在中子物质中，量子化的超流体涡旋出现了。在双味稠密夸克物质中，携带色磁通的涡旋与分数量子化的超流环流一起出现为最稳定的构型，我们称之为非阿贝尔爱丽丝弦。我们发现，三个整数中子超流涡和三个非阿贝尔爱丽丝弦的不同颜色的磁通量与总的颜色通量抵消了加入一个交界处称为Boojum。
Alice and Boojums are both representative characters created by Lewis Carroll. We show that they possibly meet in cores of rotating neutron stars. Recent studies of quark-hadron continuity suggest that neutron superfluid matter can connect smoothly to two-flavor symmetric quark matter at high densities. We study how this can be maintained in the presence of the vortices. In the neutron matter, quantized superfluid vortices arise. In the two-flavor dense quark matter, vortices carrying color magnetic fluxes together with fractionally quantized superfluid circulations appear as the most stable configuration, and we call these as the non-Abelian Alice strings. We show that three integer neutron superfluid vortices and three non-Abelian Alice strings of different color magnetic fluxes with total color flux canceled out are joined at a junction called a Boojum.
