摘要
拓扑节线与节面金属指的是在费米能附近存在能带交叉,并且这些交叉点在动量空间分别形成一维曲线和二维曲面的金属材料.这种特殊的能带结构可以带来很多奇异的物理性质,使得这两类体系在近几年得到了广泛关注.本文着重讨论了节线与节面金属相关概念的发展,回顾了有关的研究工作,包括节线与节面的特征与分类以及相应材料的预测.
Electronic band crossing can not only form zero-dimensional nodal points,but also one dimensional nodal lines and two dimensional nodal surfaces.These topological band features have been attracting significant research interest,as they may lead to many special physical properties.In this article,we review the progress in this field,including the conceptual development,the character and classification of these nodal structures,and the material realization.
