摘要

The quasi-localized charge approximation is used to calculate the wave spectrum of the magnetized three-dimensional strongly coupled one-component plasma at arbitrary angles θ between the wave vector and the magnetic field axis. Three frequency branches are identified whose interplay is strongly determined by β = ω c / ω p, the ratio of the cyclotron frequency ω c, and the plasma frequency ω p. The frequency dispersion relations for the three principal modes along the magnetic field cross in the case β < 1, which strongly affects the transition from parallel to perpendicular wave propagation. For β > 1, the frequencies of the different branches are well separated, and the long-wavelength dispersion in the intermediate and upper branch changes sign as θ is varied from 0 to π / 2. In addition to the frequencies, we also investigate the waves' polarization properties.
