Quantum hydromagnetic waves in a spin complex plasma

In this paper, the hydromagnetic waves are studied in a degenerate complex magnetoplasma environment taking into account the quantum forces related to the electron spin and the quantum potentials of the ions and electrons. To this end, a modified quantum fluid formalism including the quantum density fluctuations and spin magnetization energy is employed to analyze the dispersive properties of the wave modes. The results show that the presence of dust particles as well as quantum corrections significantly alter the behavior of the waves. In other words, the dispersion of waves decreases with the mass of dust particles. Also, the corrections due to the density fluctuations of ions and electrons have significant effects and introduce non-linear terms in the dispersion relation. In addition, the effect of the electron spin reduces the contribution of other quantum potentials on the dispersion of wave modes. Finally, some special limiting cases are discussed.
