Description

Theoretical investigation of the nonlinear dynamic of the low-frequency Buneman instability of a current-driven plasma is presented. In the nonlinear stage, this instability is described by the diffusion equation with a negative nonlinear diffusion coefficient. As a result, the plasma density profile reaches a sharp peak and is accompanied by the breakdown of quasineutrality and establishment of stationary self-focusing structures
