论文摘要
已经预测了具有带触点线的导体的高频电导率的新型角振荡。该效果是由费米表面自我交流点附近的电荷载体组引起的，那里的电子能谱接近线性，并且可以通过各向异性狄拉克锥模型来描述。共振峰的幅度满足简单的总和规则。由于磁场的倾斜角度而改变狄拉克锥各向异性程度的易度性使所考虑的振荡类型可吸引相对论效应的实验性观察
A new type of angular oscillations of the high-frequency conductivity for conductors with a band-contact line has been predicted. The effect is caused by groups of charge carriers near the self-intersection points of the Fermi surface, where the electron energy spectrum is near-linear and can be described by anisotropic Dirac cone model. The amplitude of the resonance peaks satisfies the simple sum rule. The ease in changing the degree of anisotropy of the Dirac cone due to the angle of inclination of the magnetic field makes the considered type of oscillations attractive for experimental observation of relativistic effects
