Influence of Landau quantization and temperature degeneracy on drift acoustic waves in electron-positron-ion plasmas

Coupled linear and nonlinear drift ion acoustic waves are studied in a dense degenerate, inhomogeneous electron positron ion plasma with a quantized magnetic field. The influence of the magnetic field quantization parameter, temperature degeneracy, density inhomogeneity, and positron concentration i...

Description
Summary:Coupled linear and nonlinear drift ion acoustic waves are studied in a dense degenerate, inhomogeneous electron positron ion plasma with a quantized magnetic field. The influence of the magnetic field quantization parameter, temperature degeneracy, density inhomogeneity, and positron concentration is elaborated with appropriate plasma parameters on linear and nonlinear drift ion acoustic wave propagation. The illustrations show that both linear and nonlinear wave characteristics are modified significantly by these effects. This investigation can be supportive to understand the planetary interiors, plasmonics, short pulsed petawatt laser technology, and the white dwarf stars.
