Excitation of Dissipative Drift Turbulence in Dusty Plasmas

Drift instability in dusty plasma due to plasma density inhomogeneity and inhomogeneities of dust distributions in densities and charges is studied analytically. An explicit general expression for the growth rate of instability is derived. It is found that the growth rate of the dissipative drift instability is substantially enhanced and the threshold of the instability is lowered in the presence of dust.
