A first-principles study of the collective oscillation spectrum of a strongly correlated one-component plasma in a strong magnetic field is presented. The spectrum consists of six fundamental modes that are found to be in good agreement with results from the quasilocalized charge approximation. At high frequencies, additional modes are observed that include Bernstein-type oscillations and their transverse counterparts, which are of importance for the high-frequency optical and transport properties of these plasmas.
本文对强磁场中强关联单组分等离子体的集体振荡谱进行了第一性原理研究。该谱由六个基本模式组成,与准局域电荷近似的结果吻合较好。在高频下,还观察到了包括 Bernstein 型振荡及其横向对应物在内的附加模式,这些模式对于这些等离子体的高频光学和输运性质非常重要。
