We calculate the extremal cross-sectional areas and cyclotron masses for the Fermi-surface pockets in Dirac and Weyl topological semimetals. The calculation is carried out for the most general form of the electron energy bands in the vicinity of the Weyl and Dirac points. Using the obtained formulas, one can find parameters characterizing the Dirac and Weyl electrons in the topological semimetals from appropriate experimental data. As an example, we consider the W1 electrons in TaAs.

通过振荡效应分析拓扑半金属中的Dirac点和Weyl点

我们计算了狄拉克和韦尔拓扑半金属中费米表面凹坑的截面积和回旋加速器质量。对于Weyl和Dirac点附近的电子能带的最一般形式进行计算。使用获得的公式，可以从适当的实验数据中找到表征拓扑半金属中狄拉克和魏尔电子的参数。例如，我们考虑TaAs中的W1电子。
