Coupled drift-Alfven-Shukla-Varma modes in quantum dusty plasmas
- Department of Mathematics, Visva-Bharati University, Santiniketan 731 235 (India)
A set of nonlinear equations that governs the dynamics of quantum drift-Alfven waves (QDAWs) in a nonuniform quantum dusty plasma, which consists of electrons, positive ions, and stationary negatively charged dust grains, is derived using a quantum magnetohydrodynamic model. In the linear limit, Fourier transformation of these equations yields the dispersion relation that exhibits a coupling between QDAWs and the Shukla-Varma mode. The dispersion relation is then analyzed numerically to ascertain the real wave frequencies and the growth/damping rates.
