A coupled linear dispersion relation for the basic electrostatic and electromagnetic waves in the ultracold nonuniform magnetized dense plasmas has been obtained which interestingly is analogous to the classical case. The scales of macroscopic phenomena and the interparticle quantum interactions are discussed. It is important to point out that hydrodynamic models cannot take into account strong quantum effects and they are not applicable to very dense plasmas. The analysis is presented with applications to dense plasmas which are relevant to both laboratory and astrophysical environments.

    The propagation of dust-acoustic solitons in an inhomogeneous plasma is studied for the case in which the equilibrium dust density is a constant but the equilibrium dust charge is spatially nonuniform and determined by the self-consistent charging equation. It is shown that the amplitude of the...
