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 (ε), a modulational instability appears even for classical temperatures. When the phonon damping is O (ε2)), we find that in...
