论文摘要
我们提出了Weyl Semimetals中电荷密度波（CDW）状态的理论及其与手性异常的相互作用。特别是，我们证明了最短的cdw状态的特殊性质，当韦伊尔节点之间的分离等于一半的原始互惠晶状体载体时，这是获得的。它的拓扑特性与所有其他Weyl CDW状态不同。我们在该观察结果与三维分数量子霍尔状态之间建立了联系，最近提议在磁性Weyl半学中存在。
We present a theory of charge density wave (CDW) states in Weyl semimetals and their interplay with the chiral anomaly. In particular, we demonstrate a special nature of the shortest-period CDW state, which is obtained when the separation between the Weyl nodes equals exactly half a primitive reciprocal lattice vector. Its topological properties are shown to be distinct from all other Weyl CDW states. We make a connection between this observation and the three-dimensional fractional quantum Hall state, which was recently proposed to exist in magnetic Weyl semimetals.
