Dipolar and chain of vortices in quantum plasmas with electrons exchange-correlation effects

The study of linear and nonlinear drift ion acoustic waves in a quantum plasma with electrons exchange correlation and pressure degeneracy effects is presented. A modified linear dispersion relation is obtained for an inhomogeneous degenerate plasma. In the nonlinear regime, dipolar and chain of vor...

description	The study of linear and nonlinear drift ion acoustic waves in a quantum plasma with electrons exchange correlation and pressure degeneracy effects is presented. A modified linear dispersion relation is obtained for an inhomogeneous degenerate plasma. In the nonlinear regime, dipolar and chain of vortices of drift ion waves are investigated. It is noticed that the amplitude of the dipolar vortices increases as the drift velocity decreases. The present results are compared with the previous studies. The relevance of the research work to laboratory and astrophysical plasmas is also pointed out.
