Abstract
The nonlinear interaction between the electron-positron
pairs produced by an electromagnetic wave in plasma and the wave
leads to damping of the wave, frequency upshift, change of
polarization and particle acceleration. The case of a circularly
polarized wave is investigated in the framework of the
relativistic Vlasov equation with a source term based on the
Schwinger formula for the pair creation rate.
