摘要：
Dispersion properties of kinetic Alfv,n wave in quantum magnetoplasma are derived. The quantum contribution to the Landau damping of kinetic Alfv,n wave is also derived by using linearized Vlasov equation which contains the Bohm quantum potential. Classical Landau damped kinetic Alfv,n waves play an important role in turbulence of astrophysical plasmas. The quantum modification in Landau damping of kinetic Alfv,n wave can also play a significant role in changing the scaling law of turbulent spectra as well as the formation of damped localized Alfv,nic structures in dense astrophysical plasmas.
