摘要:
The longitudinal and transverse waves of 2D magnetized complex plasma based on the drivendissipative. Langevin dynamics simulation are investigated. The modified Yukawa potential with including the magnetization of background ions is used to account for the interaction of the charged dust particles. The simulation results are compared with the existing theories including quasi localized charge approximation and randomphase approximation. In the weak magnetization regime, the wave spectra obtained from Yukawa simulation and modified Yukawa simulation basically are the same. In the strong magnetization regime, the magnetization of background ions and temperature ratio of background electrons to background ions play effects on the wave spectra of the system, particularly for the strongly coupled state. The dust acoustic waves in the weakly coupled state basically are not influenced by the magnetization of background ions.
