Abstract

Plasma oscillation and soliton wave in spatially inhomogeneous electric fields

We study the back-reaction of electron-positron pairs created in spatially inhomogeneous electric fields, based on pair-production rate, Maxwell equations, conservations of particle-number and energy-momentum. Numerically integrating a set of partial differential equations. we find that electric field and charged current are oscillating in space and time, leading to a soliton-like wave propagating in the direction of electric field gradient. In the Sauter field case, we present a detailed analysis describing properties of such soliton-like wave.
