Growth Rates of Envelope Modulations of Electromagnetic Waves in Relativistic Temperature Electron-Positron Plasmas, Stimulated by Weak Or Finite Phonon Damping

We study the modulational instability of an electron-positron plasma with relativistic temperatures and phonon damping. It is shown that when the phonon damping is O(1) or O([straight epsilon]), a modulational instability appears even for classical temperatures. When the phonon damping is O([straigh...

Summary:We study the modulational instability of an electron-positron plasma with relativistic temperatures and phonon damping. It is shown that when the phonon damping is O(1) or O([straight epsilon]), a modulational instability appears even for classical temperatures. When the phonon damping is O([straight epsilon]^sup 2^)), we find that in the non-relativistic limit, previous results are recovered, and for ultrarelativistic temperatures, the instability occurs in a wider band around the relativistic plasma frequency.[PUBLICATION ABSTRACT]
