Abstract:
Interest in quantum plasma has been developed due to its applications in ultra-small electronic devices,
laser-plasma, and dense astrophysical plasmas. Vast research has been done in Quantum plasmas
with high densities and low temperature but quantum effects can’t be neglected in modest density,
high-temperature plasmas which we normally consider as classical plasmas. Due to a high number
density in quantum plasma electron plasma frequency become extremely high and it exceeds electron
collision frequency. Because of these properties, new effects are generated in a plasma. Shear Alfven
Waves (low frequency, long wavelength) in quantum dusty magnetoplasma have been studied using
the quantum magnetohydrodynamic model (QMHD), which considers numbers of forces like Lorentz
force, Bohm potential, Quantum force etc. A modified dispersion relation for Shear Alfven waves is
formed while considering electrons and ions, magnetized and electrons are also considered quantized.
Dust is considered to be magnetized in the first case and unmagnetized in the second case.
