论文摘要
二进制复合物等离子体由两个不同物种的微粒组成,可以在某些条件下形成二维方形晶格。假设平面外模式被强垂直限制抑制了平面模式,则为纵向和横向内模式得出了平方晶格波的分散关系。将结果与Langevin动力学模拟中获得的光谱进行了比较。此外,我们研究了分散关系对两个粒子物种的电荷比和质量比的依赖性。
Binary complex plasmas consist of microparticles of two different species and can form two-dimensional square lattices under certain conditions. The dispersion relations of the square lattice waves are derived for the longitudinal and transverse in-plane modes, assuming that the out-of-plane mode is suppressed by the strong vertical confinement. The results are compared with the spectra obtained in Langevin dynamics simulations. Furthermore, we investigate the dependence of the dispersion relation on the charge ratio and mass ratio of the two particle species.
