简介：拓扑的半金属是量物质的最新发现的状态，它从绝缘体扩大了拓扑的状态的概念到金属并且在最近的年里吸引了大研究兴趣。一般来说，有三种拓扑的半金属，也就是迪拉克半金属，Weyl半金属，和节的线半金属。节的线半金属能为另外的拓扑的状态被看作先锋状态。例如，从如此的节的线开始说，节的线结构可能演变为Weyl点，把点变换成迪拉克，或由介绍联合的纺纱轨道(SOC)或集体术语成为拓扑的绝缘体。在这篇评论论文，我们介绍显示出节的线半金属状态的理论材料，包括所有碳Mackay-Terrones水晶(MTC)，anti-perovskiteCu3PdN，压的黑磷，和材料的帽子3家庭，并且我们在场为获得物质的如此的新奇状态的设计原则。
