V. Muñoz,
Relativistic Plasmas: Parametric decays Nonextensive Statistics: Part 1.
|
In relativisitic plasmas, dispersion relations are solved with pump wave and existance of ambient magnetic field.
In order to see kinetic effect, momenum distribution of particles are introduced as Maxwell distribution.
Growth rate is numerically estimated near pump wave, comparing with in fluid case.
