Nonlinear evolution of a relativistically strong electromagnetic wave in self-created electron-positron plasma
The nonlinear interaction between the electron-positron pairs produced by an electromagnetic wave in plasma and the wave leads to dam** of the wave, frequency upshift, change of polarization, and particle ac...
