Show affiliationsA linear dispersion relation for electrostatic quantum drift and acoustic waves has been found for dense electron–positron–ion magnetoplasmas. Both the fermion and thermal temperature effects have been considered for electrons and positrons. In the nonlinear regime, a stationary solution in the form of dipolar vortices has been obtained. For illustration, the results were applied to the astrophysical plasma of the atmosphere of neutron stars/pulsars.
