A new electromagnetic wave in a pair plasma

摘要

A new nonlinear electromagnetic wave mode in a plasma is reported. Its existence depends on the interaction of an intense circularly polarized electromagnetic wave with a, plasma, where quantum electrodynamical photon-photon scattering is taken into account. As an illustration, we consider a pair plasma and.,how that the new mode can be significant in astrophysical settings and in the next generation of laser-plasma, systems.
