不同类型的Lifshitz跃迁由动量空间中的拓扑控制。它们涉及随着费米面、Weyl点和Dirac点、节线的拓扑变化而发生的拓扑跃迁,以及完全能隙状态之间的跃迁。
Different types of Lifshitz transitions are governed by topology in momentum space. They involve the topological transitions with the change of topology of Fermi surfaces, Weyl and Dirac points, nodal ines, and also the transitions between the fully gapped states.
