论文摘要
考虑了放置在量化磁场中的狄拉克半金属中电磁集体激发的光谱。我们已经使用能量和动量保护定律发现了Landau阻尼区，以在电子激发的一粒子状态之间进行过渡。分析降水区域窗口边界附近的纵向和横向波的分散方程揭示了不同类型的集体激发。我们还指出了具有线性分散电子光谱的系统中磁场变化的环环吸收的普遍扩展的特征。获得的光谱的使用还使我们能够预测磁光学现象领域中的许多振荡和共振效应。
The spectrum of electromagnetic collective excitations in Dirac semimetals placed in a quantizing magnetic field is considered. We have found the Landau damping regions using the energy and momentum conservation law for allowed transitions between one-particle states of electron excitations. Analysis of dispersion equations for longitudinal and transverse waves near the window boundaries in the Landau damping regions reveals different types of collective excitations. We also indicate the features of universal broadening of cyclotron absorption for a magnetic field variation in systems with linear dispersion of the electron spectrum. The use of the obtained spectrum also allows us to predict a number of oscillation and resonance effects in the field of magneto-optical phenomena.
