    "abstract": "A kinetic equation describing the nonlinear evolution of intense\nelectromagnetic pulses in electron-positron (e-p) plasmas is presented. The\nmodulational instability is analyzed for a relativistically intense partially\ncoherent pulse, and it is found that the modulational instability is inhibited\nby the spectral pulse broadening. A numerical study for the one-dimensional\nkinetic photon equation is presented. Computer simulations reveal a\nFermi-Pasta-Ulam-like recurrence phenomena for localized broadband pulses. The\nresults should be of importance in understanding the nonlinear propagation of\nbroadband intense electromagnetic pulses in e-p plasmas in laser-plasma systems\nas well as in astrophysical plasma settings.",
