Query: Quantum Electrodynamical Effects in Dusty Plasmas   A new nonlinear electromagnetic wave mode in a magnetized dusty plasma is
predicted. Its existence depends on the interaction of an intense circularly
polarized electromagnetic wave with a dusty plasma, where quantum
electrodynamical photon-photon scattering is taken into account. Specifically,
we consider a dusty electron-positron-ion plasma, and show that the propagation
of the new mode is admitted. It could be of significance for the physics of
supernova remnants and in neutron star formation.
