论文摘要
我们研究了淋巴结半径的两个带触点线的交叉点附近的电子光谱，费米表面及其特征。特别是，计算了极端横截面和适当的回旋质量。我们还发现与交叉点附近的电子轨道相关的量子振荡的相位。所有这些量的分析都是在没有和考虑自旋轨道相互作用的情况下进行的。为了说明所获得的结果，我们将它们应用于发生淋巴结线的ZRSI。
We investigate the electron spectra, Fermi surfaces and their characteristics near crossing points of two band-contact lines in nodal-line semimetals. In particular, the extremal cross-sectional areas, and the appropriate cyclotron masses are calculated. We also find the phase of the quantum oscillations associated with the electron orbits near the crossing point. The analysis of all these quantities is carried out both without and with consideration of the spin-orbit interaction. To illustrate the obtained results, we apply them to ZrSiS in which the crossing of the nodal lines occurs.
