论文摘要
本文认为在存在强磁场的情况下,在复杂费米表面上的电子的半经典动力学。这种动力学的一般拓扑结构的重建伴随着特殊形式的封闭极端轨迹的出现,与费米表面的几何形状和拓扑密切相关。对此类轨迹的振荡现象的研究尤其允许提出一种相对简单的方法来完善具有复杂费米表面的金属中分散关系的参数。
The paper considers the semiclassical dynamics of electrons on complex Fermi surfaces in the presence of strong magnetic fields. The reconstructions of the general topological structure of such dynamics are accompanied by the appearance of closed extremal trajectories of a special form, closely related to geometry and topology of the Fermi surface. The study of oscillation phenomena on such trajectories allows, in particular, to propose a relatively simple method for refining the parameters of the dispersion relation in metals with complex Fermi surfaces.
