Weibel instability
Appearance
The Weibel instability is a plasma instability present in homogeneous or nearly-homogeneous electromagnetic plasmas plasmas which possess an anisotropy in momentum space. In the linear limit the instability causes exponential growth of electromagnetic fields in the plasma which help to restore momentum space isotropy. In the limit of an extremely anisotropic distribution the Weibel instability is related to 1 or 2 dimensional stream instabilities.
