论文摘要
我们讨论了具有基本代表性字段的仪表理论中希格斯和限制政权的条件。人们普遍认为,除非通过实现全球对称性来区分这些制度,否则它们是平稳的连接。但是,我们表明,当$ u(1)$全局对称性在\ emph {两者}中自发折断时,限制性和希格斯制度时,两个阶段可以通过相边界进行分离。两种状态之间的相变可以通过新型的拓扑涡流顺序参数检测到。我们首先通过在三个时空维度中的量规理论中的明确计算来说明这些想法。然后,我们展示了我们的分析如何概括为四个维度,这意味着核物质和夸克物质是QCD的明显不同阶段,而$ su(3)$风味对称性。
We discuss the conditions under which Higgs and confining regimes in gauge theories with fundamental representation matter fields can be sharply distinguished. It is widely believed that these regimes are smoothly connected unless they are distinguished by the realization of global symmetries. However, we show that when a $U(1)$ global symmetry is spontaneously broken in \emph{both} the confining and Higgs regimes, the two phases can be separated by a phase boundary. The phase transition between the two regimes may be detected by a novel topological vortex order parameter. We first illustrate these ideas by explicit calculations in gauge theories in three spacetime dimensions. Then we show how our analysis generalizes to four dimensions, where it implies that nuclear matter and quark matter are sharply distinct phases of QCD with an approximate $SU(3)$ flavor symmetry.
