Analytical spectrum of nonlinear Thomson scattering including radiation reaction

Understand

Accelerated charges emit electromagnetic radiation and the consequent energy-momentum loss alters their trajectory.

• This phenomenon is known as radiation reaction and the Landau-Lifshitz (LL) equation is the classical equation of motion of the electron, which takes into account radiation-reaction effects in the electron trajectory.
• By using the analytical solution of the LL equation in an arbitrary plane wave, we compute the analytical expression of the classical emission spectrum via nonlinear Thomson scattering including radiation-reaction effects.
• Both the angularly-resolved and the angularly-integrated spectra are reported, which are valid in an arbitrary plane wave.
