Radiation Reaction Friction: I. Resistive Material Medium: https://arxiv.org/abs/2004.09634
Martin Formanek, Andrew Steinmetz, Johann Rafelski
We explore a novel method of describing the radiation friction of particles traveling through a mechanically resistive medium. We introduce a modified metric in a form that assures that charged particle dynamics occurs subject to radiative energy loss described by the Larmor formula. We compare our description with the Landau-Lifshitz-like model for the radiation friction and show that the established model exhibits non-physical behavior. Our approach works as expected predicting in the presence of large mechanical friction an upper limit on radiative energy loss being equal to the energy loss due to the mechanical medium resistance.
