The effect of quantum recoil on the low-frequency electrostatic surface waves on a semi-bounded quantum turbulent plasma is investigated based on the kinetic dielectric permittivity of a plasma where the wave frequency is in the range of ion-acoustic wave. The dispersion relation and the damping rate of the surface wave are derived by employing the specular reflection boundary condition and the transverse truncation method. It is shown that the frequency of surface wave is enhanced by the quantum recoil for both non-degenerate and degenerate cases. The magnitude of damping rate is also increased by the quantum effect. The quantum recoil effect on the wave propagation is significantly reduced as the wave number becomes small. In the range of such small wave numbers, the diffusional dissipation becomes more important for the wave propagation.

具有量子反冲作用的湍流量子等离子体中离子声表面波的传播:横向截断法

基于波频率在离子声波范围内的等离子体的动态介电常数,研究了量子反冲对半有界量子湍流等离子体中低频静电表面波的影响。采用镜面反射边界条件和横向截断法推导出面波的色散关系和阻尼率。结果表明,在非简并和简并情况下,量子反冲都增强了表面波的频率。阻尼率的大小也因量子效应而增加。随着波数变小,对波传播的量子反冲效应显着降低。在如此小的波数范围内,扩散耗散对于波的传播变得更加重要。
