Low frequency modes of propagation in strongly coupled degenerate dusty plasma

Abstract

In the present work, the dust acoustic modes of strongly coupled quantum plasma have been examined considering the dust polarization force with degenerate electron and ion species. We have incorporated the statistical and diffraction effects of all the three plasma species i.e. electron, ion and dust grains. The normal mode analysis technique is used to obtain the general dispersion relation. Further, the general dispersion relation is discussed analytically as well as numerically for hydrodynamic and kinetic regimes. The numerical results for the strongly coupled degenerate plasma have been shown to see the effect of polarization force on dust acoustic modes.
