Abstract

The excitation of electrostatic high frequency surface waves (SWs), in semi bounded magnetized plasma, is examined using a quantum hydrodynamic (QHD) model. Various quantum effects are taken into account including the recoil effect, Fermi degenerate pressure and exchange–correlation potential. A general analytical expression for dispersion relation is derived using the linearized QHD model in conjunction with Poisson’s equation in the presence of a static magnetic field. It is noted that the exchange and correlation effects make to decrease the other effects of quantum (Bohm potential and thermal Fermi) and wave frequency is shifted to lower frequencies. Also, it is found that the group velocities of the modes of small wavelengths are very large with higher quantum effects. But in the case of the long wavelength modes they are higher with small quantum effects. Wide ranges of applications in plasma diagnostics, laser physics and atomic spectroscopy, inertial confinement fusion, solar corona, etc., have made SW’s investigation as one of the important quantum research areas.

半有界量子等离子体交换相关效应下的静电表面模式

利用量子流体力学模型研究了半有界磁化等离子体中静电高频表面波的激发。考虑了各种量子效应，包括反冲效应、费米简并压力和交换相关势。利用线性化的QHD模型，结合泊松方程，导出了在静磁场作用下色散关系的一般解析表达式。注意到交换效应和相关效应使量子的其他效应(玻姆势和热费米)减弱，波的频率向更低的频率移动。此外，还发现小波长模的群速度非常大，量子效应较高。但在长波模式下，它们在小量子效应下更高。在等离子体诊断、激光物理与原子光谱学、惯性约束聚变、日冕等领域的广泛应用，使SW的研究成为重要的量子研究领域之一。
