Abstract

The nonlinear coupling between photons and non-resonant density perturbations in an electron-positron plasma is considered, taking into account the relativistic particle mass increase and the photon ponderomotive force. A pair of equations comprising a nonlinear Schrödinger equation for the photons and a driven (by the photon ponderomotive force) density response is derived. It is shown that the stationary solutions of the nonlinear equations can be represented as a photonic vortex and a photon bullet.
