THPMN002  Nonlinear Dynamics of Electromagnetic Pulses in Cold Relativistic Plasmas  2707 


Funding: CNPq, Brasil In the present analysis we study the self consistent propagation of nonlinear electromagnetic pulses in a one dimensional relativistic electronion plasma, from the perspective of nonlinear dynamics. We show how a series of Hamiltonian bifurcations give rise to the electric fields which are of relevance in the subject of particle acceleration. Nonlinear coupling of plasma waves and electromagnetic pulses triggers strong chaotic dynamics which may detrap the plasma wave from the electromagnetic pulse, leading to wave breaking. Connections with results of earlier analysis are discussed.
