High-frequency photons traveling in plasma exhibit a linear polarizability that can influence the dispersion of linear plasma waves. We present a detailed calculation of this effect for Langmuir waves as a characteristic example. Two…

The radiation formation length for relativistic particles, $l_c \sim \gamma^2 \lambda$ ($\gamma$ is the Lorentz factor, $\lambda$ is the emitted wavelength), is much lager than the inter-particle distances in many astrophysical…
