TL;DR: In this paper, a multiscale technique is employed to solve the fluid Maxwell equations describing weakly nonlinear circularly polarized electromagnetic pulses in magnetized plasmas, and a nonlinear Schr?dinger (NLS) type equation is shown to govern the amplitude of the vector potential.

TL;DR: Calculations presented here in the weakly relativistic limit clearly show that under very general initial conditions, a relativistically intense wave will always phase mix and eventually break at arbitrarily low amplitudes, in a time scale omegapetaumix.

TL;DR: In this article, a numerical fluid simulation investigation of the temporal evolution of a special class of traveling wave solutions of the one-dimensional relativistic cold plasma model is reported, and issues pertaining to their stability, mutual collisional interactions, and propagation in an inhomogeneous plasma medium are addressed.

TL;DR: In this article, a numerical fluid simulation investigation of the temporal evolution of a special class of traveling wave solution of the one dimensional relativistic cold plasma model is reported, which consist of coupled electromagnetic and plasma waves in a solitary pulse shape.

TL;DR: Saxena et al. as mentioned in this paper showed that the instability can be understood on the basis of the stimulated Raman scattering phenomenon and the occurrence of density bursts in the trailing edge of the modulated structures are a manifestation of an explosive instability arising from a nonlinear phase mixing mechanism.
