论文摘要
我们解决了具有超流量的希格斯阶段中新兴的高格式对称性。如果物质字段在量规和全局$ \ mathrm {u}（1）$ symmetries的转换下不变，则会出现紧急对称性。我们明确地构建了在低能量有效理论中拓扑和规格不变的对称发生器。这种紧急的对称性有助于区分具有超流体的希格斯和其他阶段，例如有限密度的QCD阶段。我们还讨论了这些阶段之间相变的可能性。
We address emergent higher-form symmetry in Higgs phases with superfluidity. The emergent symmetry appears if a matter field is invariant under a transformation of a common subgroup of gauge and global $\mathrm{U}(1)$ symmetries. We explicitly construct the symmetry generator that is topological and gauge invariant in a low-energy effective theory. Such emergent symmetry is helpful to distinguish the Higgs and other phases with superfluidity, such as phases of QCD at finite density. We also discuss the possibility of phase transition between these phases.
